the benefit of U.S. patent application Ser. No. 11/423,259, filed
Jun. 9, 2006, which claims the benefit of U.S. Provisional
Application Ser. No. 60/728,468, filed Oct. 20, 2005. The present
application herein incorporates U.S. patent application Ser. Nos.
11/703,066, 11/423,259 and U.S. Provisional Application Ser. No.
60/728,468 by reference in their entirety.
[0002] The present application is also related to a commonly
assigned, co-pending U.S. patent application Ser. No. 11/880,458,
filed Jul. 20, 2007, incorporated herein, by reference in its
entirety.
BACKGROUND
[0003] Prepared foods, such as those appearing in supermarkets,
take-out establishments, and the like, while appearing to be home
cooked, may be typically expensive. Additionally, like fast food,
these prepared foods lack nutritional value, and may be usually
high in calories, salt, and fat. Accordingly, both fast food and
prepared foods do not appeal to health conscious consumers.
[0004] To address some of the problems of intermixed frozen meals,
a food container for use in a microwave with an internal separator
dividing the container into upper and lower compartments were
developed. The upper compartment may be configured for a food
product and the lower for a water or water-containing medium. The
separator may be a thin perforated sheet that may be designed to
snap into place with evenly spaced internal lugs. When the food
container may be placed in the microwave and heated the steam
created by the water medium passes through the separator to steam
the product. The problem with this food container may be that the
separator may be configured to latch into place for use with the
container, thereby inhibiting the availability of the
water-containing medium after the food product may be steamed.
[0005] Therefore a need still exists for an ovenable cooking
apparatus that facilitates improved cooking of a food product in
microwave ovens, conventional ovens, combination ovens and all
other typical cooking apparatuses which separates the food product
from the sauce or liquid and allows the consumer to easily access
the food product and sauce after cooking.
[0006] There exists a similar need for improvements in the food
service industry. The food service industry currently prepares food
in commercial settings using foodservice tray pans that include a
mixture of food ingredients. Typically, the food comprises a frozen
mass of ingredients such as starch, protein, vegetables, and sauce.
To prepare and serve the food, the frozen foodservice tray may be
heated in an oven, commercial oven, convection oven, combination
oven, microwave oven, steam cooker, or the like. Because the food
ingredients may be frozen in a large mass, the heating times can be
from one to two hours or more. The quality of the food using this
method may sometimes be undesirable, resulting in overcooked or
undercooked ingredients, variation in food texture, or
discoloration of the food ingredients. Further, consumers cannot
plate their meals according to their individual tastes because all
the ingredients may be mixed together. The current method may be
also incompatible with breaded ingredients because they come out
soggy and do not meet consumer approval.
[0007] Accordingly, it would be desirable to provide a method and
apparatus for preparing food in the commercial food sector that may
be more efficient and produces higher quality food products.
SUMMARY
[0008] An ovenable cooking apparatus may comprise one or more upper
compartments and one or more lower compartments for food components
wherein one or more of the upper compartments may be perforated.
The compartments may be arranged such that a food component in an
upper compartment may be cooked by steam generated by heating a
food component in the lower compartment until at least a portion of
the food component boils. The generated steam may enter the upper
compartment through openings in the base and side walls of an upper
compartment.
[0009] An ovenable cooking apparatus may include at least first and
second substantially coplanar compartments wherein one or more
solid food components and a liquid component may be maintained in
spatial separation so as to avoid their commingling during storage
or cooking. The apparatus may further comprise conduits between the
coplanar compartments thereby permitting the transfer of steam
generated from the liquid component so as to contact the solid food
components.

DETAILED DESCRIPTION
[0085] Reference will now be made in detail to the cooking
apparatus and methods, examples of which may be illustrated in the
accompanying drawings. Throughout this document there may be
references to directions and positions. These directional and
positional references may be to the apparatus in typical
orientations. The references include upper, lower, top, bottom,
above, below, and may be exemplary only. They may be not limiting
in any way, as they may be for description and explanation
purposes. The terms "cooking" and "heating," and variations
thereof, may be collectively known as "cooking."
[0086] An ovenable cooking or heating apparatus may be suitable for
use with conventional, convection, combination, or microwave ovens
as well as steamers. The apparatus may have separate compartments
for different foods or food components, such that the separateness
and integrity of each food type may be maintained from processing
(filling and packaging) through storage and cooking.
[0087] The second or upper compartment may be received by the first
or lower compartment such that after the food product may be
heated, the compartments may be easily separated. The apparatus may
also include a sheet of barrier material sealing the combined
compartments and food products.
[0088] As the apparatus may be heated, at least a portion of a
first food component in the first or lower compartment boils
producing steam. The first food component may comprise liquids,
gels, partially liquid or gelatinous compositions, and mixtures
thereof (hereinafter collectively referred to as "liquid
components"). Examples of such liquid components may include
sauces, gravies, solid food components in sauces or gravies,
broths, juices, beer, wine, spirits, sodas, oils, water and the
like as well as frozen, refrigerated or shelf-stable formulations
thereof. Such liquid components may also be used in dehydrated or
partially dehydrated formulations (hereinafter collectively
referred to as dehydrated liquid components) which may or may not
be subjected to rehydration.
[0089] The steam may be utilized to cook the second food component
in the upper compartment. Further, the second compartment may be
steam impermeable. The steam may rise into the second or upper
compartment thereby steam cooking the second food component. The
second or upper compartment may include a plurality of openings
that allow the steam to pass from the first and lower compartment
into the second or upper compartment. The sheet of barrier material
ensures that the food product may be cooked uniformly by preventing
the steam from escaping the compartments or dissipating into the
atmosphere during cooking. Although, the apparatus may be designed
such that the foods or food components in each of the compartments
cook simultaneously, as the compartments may be easily separated,
the consumer may choose to consume the steamed second food product
by itself or in combination with the first food component.
[0090] FIGS. 1 A-3C show an apparatus 20 for holding separate food
components to maintain the separateness and integrity of the
components during storage and cooking. The food components may be
combined after cooking by the user. Apparatus 20 may also be of any
general. Suitable shapes include circular, oval, rectangular,
square, among others. As shown in FIGS. 1A-3C, the apparatus 20 may
be of circular shape. The apparatus 20 may include a container 22
and a basket 24, that may be separate pieces, with the basket 24
constructed to be received by the container 22.
[0091] The container 22 holds a first food component. The basket
24, may be received and held by the container 22, and may be in
coaxial alignment with the container 22. The basket 24 typically,
holds a solid food component, such as starches and/or proteins,
such as rice, grains, and pasta, vegetables, or other particulate
foods, that may be typically steam cooked. Accordingly, the basket
24 may include openings 70 in its base 63 and its sidewalls 64 that
allow steam, generated by the cooking of the first component, to
enter the basket 24, and cook the second food component. The
openings 70 may be also dimensioned to allow liquids, such as water
and the like, generated in the upper compartment during cooking, to
drain into the container 22.
[0092] As shown in detail in FIGS. 2A-2C, the container 22 may
include a body 30 that may be circular in shape. The body 30 may
include an inner side 30a, and an outer side 30b. The body 30 may
include a cavity 32, defining the inner side 30a of the body, a
base 33, and sidewalls 34. The body 30 may be suitable for holding
a first food component and receiving the basket 24 in a secure
manner.
[0093] The container's 22 sidewalls 34 include a shelf portion 38
within its cavity 32. The shelf portion 38 extends along the
sidewall 34 and may be typically continuous. The sidewalls 34
typically include at least a portion that tapers outwardly, with
the entire sidewall 34 typically tapering outwardly from the base
33 to a rim 36, at the opening of cavity 32. The shelf portion 38
provides support for the basket 24 and ensures that the base 63 of
the basket 24 may be not in direct contact with the base 33 of the
container 22 (as shown in FIGS. 1 B and 1 C). The shelf portion 38
coupled with the sidewalls 34 allow for the basket 24 to be
removably received in the container 22 in a secure manner, with
minimal movement or play. Alternatively, the container's 22
sidewall 34 may include at least one ledge or protrusion rather
than a shelf portion 38 to provide support for the basket 34.
Optionally multiple ledges or protrusions may be included to
support the basket 34.
[0094] As shown in FIG. 2C, the outer side 30b of the body 30, may
include protrusion segments 44. These protrusion segments 44 allow
for ease in manually gripping the apparatus 20.
[0095] As shown in detail in FIGS. 3A-3C, the basket 24 may include
a body 60 that may be substantially circular in shape, to conform
to the shape of the container 22. The body 60 may include an inner
side 60a, and an outer side 60b. The body 60 may include a cavity
62, defining the inner side 60a, a base 63, and sidewalls 64. The
body 60 may be suitable for holding a second food component.
[0096] The sidewalls 64 typically include at least a portion that
tapers outward, with the entire sidewall 64 typically tapering
outward from the base 63, to a rim 66, at the opening of the cavity
62. The sidewalls 64 and rim 66 typically include arcs 68 that may
be typically rounded inward, into the cavity 62. The arcs 68, may
be approximately oppositely disposed with respect to each other,
and when the basket 24 sits in the container 22, serve as vents for
steam, generated in the cavity 32 of the container 22 during
cooking. The arcs 68 also provide sufficient portions for manually
gripping the basket 24, for its removal from the container 22.
[0097] The basket 24 may include a plurality of openings 70. The
openings 70 may be perforations or bores 72 that extend through the
base 63 and through the sidewalls 64. The bores 72 may be of any
size or dimension so as to allow steam to pass from the cavity 32
of the container 22 into the basket 24, in order to steam heat (or
steam cook) the contents (e.g., the second food component) stored
in the cavity 62 of the basket 24, as well as allowing liquid
(typically water) to pass from the basket 24 into the container 22.
Moreover, the openings 70 may be also dimensioned to keep
particulate foods, such as rice and the like, including particles
thereof, from dropping out of the basket 24 and into the cavity 32
of the container 22. Suitable bore shapes include small, circular,
rounded, or oval cylindrical bores, but may be not limited
thereto.
[0098] The openings 70 at the base 63 and sidewalls 64 may be
arranged in any desired pattern, provided sufficient amounts of
steam may be able to reach the basket 24 and there may be
sufficient openings 70 to allow for the passage of liquid from the
basket 24 to the container 22. The openings 70 at the base 63 may
be arranged in a series of concentric circles. The openings 70 at
the sidewalls 64 may be arranged in a line. Typically, one or more
lines of openings 70 may be included in the sidewalls 64 of the
basket 24. If a second line of openings 70 may be arranged at the
sidewalls 64, the second line of openings 70 may be offset with the
first line of openings, such that the cylindrical bores 72 of the
second line may be not directly below the cylindrical bores 72 of
the first line.
[0099] The body 60, may be constructed, such that when the basket
24 may be removably received by the container 22, there may be
sufficient space in the cavity 32 of the container 22, between the
base 33 of the container 22 and the base 63 of the basket 24, to
accommodate a first food component in both dry or frozen (storage)
and cooking (heated) states, without disrupting the seating of the
basket 24 in the container 22. Additionally, the body 60 may be
such that the basket 24 may be adequately supported in the
container by the shelf portions 38 (FIG. 1C) and the indent 46 of
the rim 36, in order that it hold the second food component,
without substantial bending and without allowing the first and
second food components to contact one another during storage, prior
to the cooking process, or during the cooking process.
[0100] FIGS. 4A-4C show an alternate basket 24', similar in all
aspects of construction and dimensions to the basket 24.
Accordingly similar components, as detailed above, may be numbered
the same as above. Changed or different components may be detailed
below.
[0101] The basket 24', like basket 24, may be substantially
circular in shape, and designed to sit in the container 22, as
detailed above. The basket 24' differs from basket 24, in that the
openings 70 may be slits 90, rather than circular, rounded, or oval
cylindrical bores 72 as in basket 24. Like the cylindrical bores
72, the slits 90 may be dimensioned to facilitate the passage of
steam, generated by cooking of the first food component, to enter
the basket 24'. The dimensioning of the slits 90 also facilitates
the passage of a liquid from the basket 24' to the container 22.
This dimensioning keeps particulate food, such as rice and the
like, and particles thereof, from dropping out of the basket 24'
and into the cavity 32 of the container 22.
[0102] The slits 90 may be typically rectangular in shape, and
extend through the base 63'. They may be typically arranged in a
parallel alignment with respect to each other. The slits 90 may be
typically oriented perpendicular to the longitudinal axis MM of the
base 63'. Alternatively, the slits 90 may also be oriented parallel
to the longitudinal axis MM of the base 63'.
[0103] FIGS. 5A-9C show an apparatus 120 of similar construction
and materials to apparatus 20 detailed above. Components in
apparatus 120 that may be similar to those in apparatus 20, FIGS.
1A-3C, may be numbered so as to be increased by "100." The
components increased by "100" that may be not described below,
function similarly to the corresponding components for apparatus
20. Different components, including components that function
differently, may be described below.
[0104] As stated above, the apparatus may be of any desired shape.
As shown in FIG. 5A, the apparatus 120 may be such that it may be
of an oval shape. The apparatus 120 may be formed of a container
122 that may be oval in shape, and a basket 124, for sitting in the
container 122, in a secure manner, as detailed above, for the
container 22 and basket 24, 24' of apparatus 20.
[0105] As shown in FIGS. 6A-6C, the container 122 may include shelf
portions 138, at an intermediate height along the sidewalls 134
that may be typically discontinuous from each other. Dividing
portions 140 that extend inward into the cavity 132, separate the
shelf portions 138 from each other. The dividing portions 140
extend from the base 133 to ledges 142, proximate to the rim 136.
The shelf portions 138 and the dividing portions 140 may be
typically symmetric and oppositely disposed with respect to each
other. The shelf portions 138 provide support for the basket 124
(as shown in FIGS. 5B and 5C). The dividing portions 140 may be
such that they provide rigidity to the container 122. The rim 136
of the container 122 also may include an indent 146, similar to the
indent 46, along the inner periphery of the rim 136. The rim serves
in maintaining a secure fit of the basket 124 in the container
122.
[0106] As shown in FIGS. 7A-7C, the basket 124 may be of a
substantial oval shape, but may include arcs 168, similar to the
arcs 68, to allow for venting of steam as well as ease of gripping,
by fingers. The basket 124 may include openings 170 of cylindrical
bores 172, arranged in lines. The cylindrical bores 172 may also be
staggered. Alternatively, other arrangements of the openings 170
may be also permissible, such as concentric circles. The openings
170 (formed of cylindrical bores 172) function similarly to the
openings 70 (formed of cylindrical bores 72) of the basket 24, as
detailed above.
[0107] The outer side 160b of the body 160 may include protrusion
segments 174. These protrusion segments 174 allow for ease of use
in manually gripping the basket 124.
[0108] FIGS. 8A-8C show an alternate basket 124', similar in all
aspects of construction to basket 124, except where indicated. The
basket 124', like basket 124, may be substantially oval in shape,
and designed to sit in the container 122, as detailed above. The
basket 124' differs from the basket 124, in that the body 160' may
be divided into two cavities 162a', 162b', for holding separate
food components. Additionally, the base 163a' of the first cavity
162a' may include openings 170 cylindrical bores 172, as detailed
above. The base 163b' of the second cavity 162b' may be solid,
whereby the food component therein may be primarily heated by the
heating source.
[0109] FIGS. 9A-9C show another alternate basket 124'', similar in
all aspects of construction and dimensions to the basket 124.
Accordingly similar components, as detailed above, may be numbered
the same as above. Changed or different components may be detailed
below.
[0110] The basket 124'', like basket 124, may be substantially oval
in shape, and designed to sit in the container 122, as detailed
above. The basket 124'' differs from basket 124, in that the
openings 170 may be slits 190.
[0111] The slits 190 may be similar in construction and function to
the slits 90 of the basket 24, as detailed above. The slits 190 may
be cut into and extend through the base 163'' of the body 160''.
They may be typically arranged in a parallel alignment with respect
to each other. The slits 190 may be typically oriented
perpendicular to the longitudinal axis LL of the base 163''.
Alternatively, the slits 90 may also be oriented parallel to the
longitudinal axis LL of the base 163''.
[0112] The containers 22,122 and baskets 24, 24',124, 124', 124''
may be made of polymers, such as Polypropylene (PP) (e.g.,
Co-polymer Polypropylene), Crystallized Polyethylene Terepthalate
(CPET), or any other microwave and food safe non-toxic material.
The containers 22,122 and baskets 24, 24', 124, 124', 124'' may be
formed by conventional polymer forming and working techniques.
Suitable forming and working techniques include injection molding,
rotational molding, and the like, as well as thermoforming. The
containers 22, 122 and baskets 24, 24', 124, 124', 124'' may be
suitable for refrigerated storage, freezer storage, and subsequent
heating without substantial deformation.
[0113] The apparatuses 20,120, in particular, the containers 22,122
and baskets 24, 24', 124, 124', 124'' may be typically of
dimensions to ensure that during the cooking process the second
food component may be uniformly steam cooked. In addition, the
apparatuses 20, 120, in particular, the containers 22,122 and
baskets 24, 24', 124, 124', 124'' may be of dimensions to fit
within a typical consumer, or alternatively, food service microwave
oven, with sufficient space remaining. The containers 22 and 122
may be of circular shape and with a diameter of from about 4 to
about 12 inches. Alternatively, the containers 22 and 122 may be of
rectangular shape, with dimensions of from about 3 to about 6
inches in width to about 7 to about 12 inches in length. In
addition, the containers 22 and 122 may include 1 to 6 servings,
preferably 2 to 4 servings. Other dimensioning and/or shapes for
the apparatuses 20,120, containers 22, 122 and baskets 24, 24',
124, 124', 124'' may be also possible, to accommodate different
packages, cartons, or sleeves, that hold the apparatus prior to its
use, as well as the internal cooking chambers of microwave ovens,
high energy cooking apparatus, and the like. Similarly, other
serving sizes may be also possible to accommodate consumer
demand.
[0114] The apparatuses 20,120 may be such that they may be covered
by a sheet of barrier material (e.g., transparent, translucent, or
opaque) continuously sealed to the rim 36 of the containers 22 and
122, but also could be sealed to the rim 66, 166 of the baskets 24,
24',124, 124', 124''. This sheet of barrier material may be made of
a material that may be suitable to withstand oven temperatures
during cooking and may be moisture-impervious. Suitable materials
include polymers, such as polypropylene and polyethylene, among
others. The sheet of barrier material may be sealed to the rim
using any method generally known in the art The sheet of barrier
material may be sealed to the rim to prevent substantial bulging or
expansion of the sheet material during the cooking process. In
particular, the seal may be such as to allow the release of some
pressure build up inside the container while maintaining uniform
heating and cooking of the food products therein.
[0115] The ovenable cooking apparatus 220 may be suitable for use
in commercial foodservice applications. FIGS. 10 through 26 show an
ovenable cooking apparatus 220 suitable for foodservice
applications. The ovenable cooking apparatus 220 may include a
basket 222 and a container 224 that may be dimensioned to allow the
basket 222 to nest inside the container 224. The container 224 may
be used for containing the first food component 234 and receiving
the basket 222, which holds the second food component 236. Use of
the ovenable cooking apparatus 220 may result in a higher quality
food product as compared to current methods in foodservice
applications without requiring significant changes to current
equipment and procedures. Use of the basket 222 and the container
224 allows separation of the sauce or liquid components of the meal
from the vegetable, starch, or protein components. This separation
leads to improvements in vegetable, protein, and starch integrity.
The separation of food ingredients also allows for the preparation
of breaded ingredients, which have typically been avoided using
conventional methods because the soggy breaded items do not meet
consumer standards. Use of the ovenable cooking apparatus 220 may
result in breaded items, such as chicken parmesan, that meet
consumer approval and may be not soggy.
[0116] The ovenable cooking apparatus 220 may include a passage for
providing airflow and steamflow for cooking the second food
component 236. These passages may be defined by the basket 222 and
the container 224, and allow an area through which steam may pass
to transfer heat and/or steam to the second food component 236. The
passage may be defined between the bottom or base 240 of the basket
222 and the top surface of the second food component 236. Cooking
the liquid-based second food component 236 generates steam, which
may travel across this passage to contact the basket 222 and heat
or steam the second food component 236. In the methods illustrated
in FIGS. 12, 13, and 15, the passage may be a rectangular prism.
However, it will be appreciated that the prism may be shaped
differently, such as in a concave shape for increasing the surface
area of the basket 222 adjacent to the passage (as depicted in FIG.
21). The passages may also take the form of openings 238 that may
be located at the base 240 of the basket 222. The openings 238 may
include apertures such as perforations, pores, holes, slits,
outlets, slots, vents, gaps, pricks, or the like to facilitate
steaming when steaming may be desired. The basket may also be solid
to prevent steam from passing (for instance, when cooking breaded
items).
[0117] FIGS. 11 through 13 depict the basket 222 that may be
suitable for foodservice applications. The basket 222 may include
openings 238 that extend through the base 240 of the basket 222.
The basket 222 may also include openings 238 along the sidewalls
250 of the basket 222. The basket 222 may also include a rolled
edge 226 along the rim 228 of the basket 222 to allow the stacking
of the rim 228 of the basket 222 along the rolled edge 230 of the
container 224. As previously discussed, the body of the basket 222
may take any shape. The basket 222 may be of a rectangular shape
with dimensions that may range from 4'' to 18'' in length, 3'' to
12'' in width, and 1'' to 8'' in depth. The basket 222 allows the
second food component 236 to be cooked separately from the first
food component 234.
[0118] FIGS. 10 through 13 show the container 224 that may be
suitable for foodservice applications. The container 224 may
include a rolled edge 230 along the rim 232 of the container 224 to
allow stacking of the basket 222 within the container 224. The
container 224 may be dimensioned to allow nesting of the basket 222
within the container 224. The dimensions of the container 224 may
range from 4'' to 18'' in length, 3'' to 12'' in width, and 1'' to
8'' in depth. The container 224 allows the first food component 234
to the cooked separately from the second food component 236.
[0119] FIGS. 3 through 6 demonstrate how the basket 222 may be
removably received within the container 224 when food may be loaded
into the ovenable cooking apparatus 220. The basket 222 may be
stacked in the container 224 and the first food component 234 may
be filled to a level to provide airspace between the base 240 of
the basket 222 and the first food component 234. As presented in
FIG. 14, the basket 222 may be stacked in the container 224 and the
first food component 234 may be filled to a level to limit or
eliminate the airspace to provide partial or complete contact
between the base 258 of the container 224 and the first food
component 234. Either configuration may be selected depending on
the type of food components, required cook times, thermodynamic
properties of the cooking method and the food components, etc. The
dimensions of the basket 222 and container 224 may vary to provide
a greater or lesser amount of airspace. Similarly, the amount of
the first food component 234 that may be loaded into the container
224 may vary to provide the appropriate amount of airspace. By
controlling air space, water, and the like, cooking times and food
attributes can be controlled.
[0120] FIG. 12 depicts how the rolled edges of the basket 222 and
the container 224 may be stacked to allow the basket 222 to nest
within the container 224. The container 224 and the basket 222 may
be formed of aluminum. The rolled edges may be formed using a
crimper using methods known in the art of foodservice tray
formation. The stackability of the basket 222 within the container
224 may be provided using another method known in the art.
[0121] Referring to FIG. 16 an ovenable cooking apparatus 220 may
include a footed basket 244 and a container 224. The footed basket
244 may further include a plurality of support members which rest
on the base 258 of the container 224. This provides airflow and
separation between the base 240 of the basket and the base 258 of
the container 224. The passage may comprise a gap that exists
between the base 240 of the basket 222 and the base 258 of the
container 224. This passage serves to facilitate and permit the
flow of steam from the first food component to the basket 222, and
thus to the second food component 236. It will be appreciated that
the support structures will be designed to minimize obstruction of
the passage. This may also be designed to work with no air gap
between the footed basket 244 and the container 224.
[0122] The footed basket 244 may be depicted in FIG. 16, and may
include a basket with a plurality of support members, which may
include ridges, contours, or foot members 246. The foot members 246
protrude from the base 240 of the basket and contact the base 258
of the container 224. The foot members 246 may be dimensioned to
keep the base 240 of the basket 222 separate from the base 258 of
the container 224. The amount of the first food component 234 that
may be loaded into the container 224 may vary to provide varying
amounts of airspace. Similarly, the size of the foot members 246
may also vary to provide varying amounts of airspace, but may be
generally sized so as not to obstruct the passage. The footed
basket 244 may include openings 238 to allow steam to enter and
drain from the basket and cook the second food component 236. The
foot members 246 may provide sufficient separability between the
container 224 and the basket to provide the passage for steam and
heat to cook the second food component 236, and openings 238 may be
not required.
[0123] Employment of the footed basket 244 may provide sufficient
support to the basket 222 so that rolled edges 226, 230 may be not
required suspend the basket 222 above the first food component 234.
This can provide certain manufacturing advantages, as modifications
to the edge crimper which typically forms the rolled edges, would
not be required. The footed basket 222 can be manufactured using a
thermoform process, aluminum press, or other method known in the
art.
[0124] Referring to FIGS. 17 through 20 a cooking apparatus may
comprise a container 224 and a basket 222 with indentations 248.
The basket 222 with the indentations 248 may be dimensioned to
provide increased steam and airflow along the periphery of the
basket 222. The indentations 248 in the sidewalls 250 of the basket
and the sidewalls of the container may serve to define the passage
for steam to cook the second food component 236. The form of the
passage may be vertical.
[0125] The basket 222 may be steam impermeable. Suitable materials
include polymers, such as polypropylene and polyethylene, among
others. For example, the basket may be formed from one continuous
material, such as a continuous sheet of metal or the like. The
basket 222 may be utilized for cooking foods that need to be
separated from the steam produced by the first food component. The
basket 222 may be utilized for cooking a foodstuff such as bread,
or the like. It will be appreciated that other foodstuffs may be
cooked in the basket 222 and separated from steam generated by the
first food.
[0126] The basket 222 may be of a generally rectangular shape as
described previously and include indentations 248 in the side walls
250 of the basket 222. The basket 222 may include two indented side
walls along the length of the basket 222. The basket 222 may
include indentations 248 along both the length of the basket 222
and along the width of the basket 222. FIGS. 19 and 20 depict a
generally rectangular basket 222 which may be removed to provide
increased airflow and steam along the corner of the basket 222.
Other configurations of indentations 248 to the basket 222 may be
also possible, and may include circular indentations, contoured
indentations, or the like on any number of the basket's sidewalls
250. The indentations 248 may result in a symmetrically shaped
basket 222, or an asymmetrically shaped basket 222.
[0127] The ovenable cooking apparatus 220 may also include a
container 224. The container 224 may be dimensioned to define the
passage and provide gaps 254 between the edge/rim of the container
224 and the rim/edge of the basket 222. These gaps 254 provide
steam flow and airflow to heat the second food component 236. It
will be appreciated that the lid 225 for the ovenable cooking
apparatus 220 may be separated form the lip of the basket 222 to
allow steam to move from the passage to the second food component
236.
[0128] Referring to FIGS. 17 through 20 the cooking apparatus 220
may also include a basket 222 with handles. The handles may include
a protrusion segment or other means to allow manual gripping of the
basket 222 for removal from the container 224. The handles may be
located on the indentations 248 at the opposing corners of the edge
of the basket 222. The handles may be located on opposing sides of
the length-wise indentation of the basket 222. Employment of the
handles may eliminate the need for rolled edges on the basket 222
and the container 224, thus providing ease in manufacturing.
[0129] Referring to FIGS. 17 through 20, a cooking apparatus 220
may provide sufficient steam flow and airflow to the basket 222 so
that openings 238 may not be required. The basket 222 may not
include openings 238. The manufacturing process for forming a
basket 222 with indentations 248 may be thus easier and cleaner
because a secondary cut for the openings 238 may be not required.
The basket 222 with indentations 248 can be formed using a
thermoform process, aluminum press, or other method known in the
art.
[0130] The ovenable cooking apparatus 220 described in FIGS. 17
through 20 may also be compatible with the footed basket 244
depicted in FIG. 16. The basket 222 may include foot members 246
and indentations 248 along the length of the basket 222. The foot
members 246 and the indentations 248 provide steam flow and air
flow to the periphery of the basket 222 to cook the second food
component 236.
[0131] Referring to FIG. 21, a cooking apparatus 220 may include a
wok-shaped basket 256 and a container 224. The basket 222 may be
formed in a wok-like or bowl-like shape. The wok-like shape may
provide enhanced thermodynamic and cooking properties for certain
food components and heating devices.
[0132] The wok-shaped basket 256 may be depicted in FIG. 21 and may
include a rolled edge 226 to allow stacking of the basket 222
within the container 224. The wok-shaped basket 256 may include
openings 238 to provide increased steam flow and drainage. The
wok-shaped basket 256 does not include openings 238 because the
shape of the wok provides sufficient air flow and steam flow to
heat the second food component 236. For example, the curvature of
the wok-shaped basket 256 may provide a larger air gap 242 along
the periphery of the wok-shaped basket 256 so air and steam can
cook the second food component 236. In some instances, the second
food component 236 may include breaded items for which steam
contact may be not desired. In such an instance, the steam
generated by the first food component 234 provides sufficient heat
transfer to the basket 256 to heat the second food component
236.
[0133] Referring to FIG. 21, the container 224 may be dimensioned
to allow nesting of the wok-shaped basket 256 in the container 224.
The container 224 may include a rolled edge 230 to allow the basket
to stack into the container 224. The amount of the first food
component 234, as well as the dimensions of the wok-shaped basket
256 and the container 224, may be varied to provide different sized
air gaps. The container 224 and the wok-shaped basket 256 may be
dimensioned such that a portion of the base 240 of wok-shaped
basket 256 may contact a portion of the base 258 of the container
224. Only a portion of the base 240 of the wok-shaped basket 256
contacts the base 258 of the container 224 or the first food
component 234, providing an air gap 242 along the edge/rim of the
wok-shaped basket 256. The base 240 of the wok-shaped basket 256
does not contact the first food component 234 or the base 258 of
the container 224, and instead may be supported by the rolled edges
to provide a larger air gap 242.
[0134] Referring to FIG. 22, a cooking apparatus 220 may include a
basket 222 and a container 224 with a contoured base 260. The
container may include a contour 262 at the base 258 of the
container, with the concavity of the contour 262 being oriented
towards the basket 222. Such a configuration may provide enhanced
heat transfer to the food components. The base of the container 224
may be shaped to extend into the passage, in close proximity to the
base of the basket 222. This may facilitate heat transfer between
the container 224 and the basket 222 by reducing the distance
between them.
[0135] As depicted in FIG. 22, the container may include a contour
262 at the base 258 of the container. In some instances, the food
components that may be located towards the center of the basket 222
and the container may be the most difficult to heat because they
receive the least amount of heat transfer. Unlike the edges of the
container, which may receive heat through the bottom and the sides
of the container, the center of the base may only receive heat from
one direction. The contour 262 may provide enhanced heat transfer
because it reduces the thickness of this center area of the
ovenable cooking apparatus 220 which may be difficult to heat. The
size and concavity of the contour 262 may vary depending on the
heat transfer desired and the type of food. Multiple contours 264
may also be included to provide enhanced heat transfer and cooking.
Referring to FIG. 24, the container may include a plurality of
contours 264 to provide a greater surface area to volume ratio on
the tray. This may provide enhanced heat transfer because a greater
surface area on the container provides a greater area for heat
transfer to occur. Other textures may also be applied to the base
258 of the container to increase the surface area for heat
transfer, including pyramidal textures, sinusoidal textures, wave
patterns, or the like.
[0136] Referring to FIG. 23, the basket 222 may also include a
contour 266 to provide enhanced heat transfer and cooking. The
contour 262 of the container may be greater than the contour 266 of
the basket 222 so that when the basket 222 may be removably
received in the container the air gap may be minimized.
[0137] Referring to FIG. 25 a cooking apparatus may include a
basket 222, container 224, and an oven bag 268. The oven bag 268
may be non-venting to increase the cooking pressures and decrease
cooking time. To prepare the food, the basket 222 may be removably
received within the container 224 and both may be cooked inside the
oven bag 268. For packaging, transport, and sale, the basket 222
and container 224 may be already packaged within the oven bag 268,
or the oven bag 268 may be included with the container 224 and
basket 222 and the user puts the container 224 and basket 222 into
the oven bag 268.
[0138] Referring to FIG. 26, an ovenable cooking apparatus 220 may
include a basket 222 that may be dimensioned to be smaller than the
container 224. The basket 222 may be less than half the size of the
container 224. Such a configuration may be used for food products
that include a greater amount of a first food component 234 (such
as sauce or sauce and vegetables) than a second food component 236
(such as starch, protein, or the like). The second food component
236 may be packaged in the basket 222, which may be smaller and
dimensioned to receive a smaller amount of food and the first food
component 234 may be packaged in the container 224. Multiple
baskets may also be included in the container 224. The container
224 and the baskets may be dimensioned to allow the container 224
to accommodate two or more baskets containing different food
components.
[0139] The ovenable cooking apparatus 220 may include a container
224 with a first basket 222 and a second basket. The container 224
holds a first food component 234, the first basket 222 holds a
second food component 236 and the second basket may hold a second
food component 236 or a third food component. The first basket 222
and the second basket may employ any of the features described
previously, including openings 238, handles, or foot members 246.
The first basket 222 and the second basket may have different
characteristics, particularly if they may be used to hold different
food components. For example, the first basket 222 may include
openings 238 to provide extra drainage and steam flow to a second
food component 236, while the second basket may not include
openings 238. The container 224 and baskets may be dimensioned to
allow several baskets to be removably received within a single
container 224.
[0140] The ovenable cooking apparatus 220 may be used according to
a number of methods. In one method, the container 224 containing
the first food component 234 and the basket 222 containing a second
food component 236 may be packaged and sold together. The basket
222 and the container 224 may be packaged in a nested fashion for
efficiency, but prepared separately. For instance, a user may be
instructed to heat the container 224 and the basket 222 separately
instead of in a nested fashion to prepare the food components. The
ovenable cooking apparatus 220 may include a container 224
containing a first food component 234 and a basket 222 containing a
second food component 236, as well as a second basket containing a
third food component. The first and second baskets may be removably
received in the container 224 during transport and sale, and during
preparation a user may separate the second basket and cook it
separately while leaving the first basket and the container 224 to
cook in a nested fashion.
[0141] The materials used to construct the basket 222 and the
container 224 may depend on the cooking mechanism, the type of
food, cost, and other factors. The materials may include all the
aforementioned materials (PP, CPET, APET, Nylon, Aluminum, etc.),
and others such as pressed paperboard, molded pulp, or the like. It
may also be possible to construct the basket 222 from one material
and the container 224 from another. For instance, the basket 222
may be constructed of polypropylene (PP) and the container 224 may
be constructed of Crystallized Polyethylene Terepthalate
(CPET).
[0142] An ovenable cooking apparatus 300 suitable for use in
multi-serve or family style applications is presented. FIGS. 29-35
show an ovenable cooking apparatus 300 suitable for such
applications. The previously disclosed cooking apparatuses (as in
FIGS. 1 and 11) generally comprise a base container (which may hold
a liquid component) and a basket (which typically holds a solid
food component or components) which may be received and held by the
container.
[0143] While this arrangement may be beneficial for single-serve or
large-batch preparation (as for food service) where all solid food
components of the product may be combined in a single compartment,
in multi-serve, family-style configurations, alternate
constructions may also be desired. The meal preparation needs of
today's busy families require convenient mechanisms for providing a
variety of food items to accommodate the varied tastes of multiple
individuals.
[0144] For example, a first individual may desire that all
components of a meal be combined in a single grouping as the
individual prefers the combined flavors and textures of various
combinations of components, as in FIG. 27. However, a second
individual may not enjoy such a combination of flavors and textures
of the components and may prefer for the components to remain
spatially separate as in FIG. 28.
[0145] As such, FIGS. 29-35 disclose multi-serve cooking
apparatuses incorporating multiple food-types which may be
physically separated and may be combined according to individual
tastes.
[0146] In FIG. 29, a multi-serve cooking apparatus 300A is
presented. The apparatus 300 may comprise a base container 301,
perforated basket-type trays 302 and/or non-perforated trays 303
which may be removably received within the base container 301.
[0147] As previously discussed, the base container 301 may hold a
liquid component. A portion of this liquid component may be
converted to a vapor phase upon heating, thereby facilitating the
cooking of food items disposed in the trays 302, 303 removably
received within the base 301.
[0148] The number and type of removably received trays 302, 303 may
be configured based on the nature of the food components which may
be disposed therein. For example, food items which require more
thermal energy to ensure adequate cooking, such as proteins, may be
disposed in a first basket-tray 302A which may be directly adjacent
to the base 301. Food components which require less thermal energy
for cooking but still benefit from the steaming characteristics
provided by a basket-type tray construction, such as fruits,
vegetables, and certain starches may be disposed in a second basket
302B. Further, components which require limited thermal energy or
may be degraded by steaming, such as breads, may be disposed in a
tray 303 having a base substantially or completely free of
perforations so as to inhibit or prohibit the interaction between
the vapor phase of the liquid component and the food components
disposed within such perforation-free compartments.
[0149] Referring to FIG. 29B, a cooking apparatus 300A' is
presented. The apparatus 300 may comprise a base container 301, and
one or more non-perforated trays 303 which may be removably
received within the base container 301.
[0150] Referring to FIG. 30A, a liquid component 304, such as a
sauce or broth, may be disposed in base container 301. A second
food component, such as a protein 305, may be disposed within
basket-tray 302A. A third component, such as a vegetable or fruit
306, may be disposed within basket-tray 302B. A fourth component,
such as a starch or grain 307, may be disposed in basket-tray 302C.
A fifth component, such as a bread 308, may be disposed within a
non-perforated tray 303.
[0151] Such a configuration may operate to create a gradient of
vapor concentration as the components adjacent to the base
container 305 will receive a greater level of steaming and
flavoring from the liquid component 304 than will those at more
distant levels 306, 307, 308.
[0152] It should also be noted that in the nesting configuration of
the cooking apparatuses 300A-B, the flanged portion of each
removably received tray rests upon the flanged portion of the tray
beneath it. However, other nesting configurations are fully
contemplated. FIG. 30B presents a configuration where the walls of
each of the removably received trays 326 may be dimensioned such
that the interior surface of a lower tray 327 may be contacted with
the exterior surface of an upper tray 328 so as to retain the upper
tray 328 in an elevated position with respect to the lower tray
327.
[0153] Referring to FIG. 30C, a base container 301, basket trays
302, and/or non-perforated trays 303 may be configured so as to sit
atop one another in a stacked configuration such that no portion of
a container or tray is received within another container or tray.
The base container 301 and trays 302 and 303 may comprise rim
portions and floor portions dimensioned such that a floor portion
of a first container 301 or tray 302, 303 may contact a rim portion
of a second container 301 or tray so as to support the first
container 301 or tray 302, 303 above the second container 301 or
tray 302, 303. The base container 301 and trays 302, 303 may
comprise support structures, such stilts, tabbed portions, or other
supporting elements such that a first container 301 or tray 302,
303 may contact the support structure of a second container 301 or
tray so as to support the first container 301 or tray 302, 303
above the second container 301 or tray 302, 303.
[0154] The base container 301 and trays 302, 303 may be maintained
in a stacked configuration through the use of an overwrap film 329.
The film overwrap may be constructed of plastics, polymers, heat
sealable papers, cellophane, foils and the like. Referring to FIG.
30D, the base container 301 and trays 302, 303 may be maintained in
a stacked configuration through the use of clips or fasteners 330
which cooperatively engage a portion of at least two of the base
container 301 and the trays 302, 303.
[0155] The level of interaction of the vapor phase of the liquid
component with subsequent components may be regulated by the size
and/or shape of the perforations of the basket-trays. FIG. 31
provides a cooking apparatus 300C comprising a base container 301
and basket-trays 302. The basket-trays 302A-C may comprise
perforations 309, 310 and 311 having respective cross-sectional
areas wherein perforations 309 may have a cross-sectional area
greater than those of perforations 310. Similarly, perforations 310
may have greater cross-sectional area than those of perforations
311. Such varied cross-sectional areas provide a mechanism for
controlling the amount of vapor which contacts a given food
component, thereby further optimizing the cook characteristics of a
particular food component.
[0156] It should be noted that the size and relative arrangement of
the perforations of trays 302A-C may be arbitrary and one skilled
in the art would necessarily recognize that such parameters may be
easily adjusted to obtain specified cooking characteristics for
individual food components and/or combinations thereof.
[0157] Referring to FIG. 32, a cooking apparatus 300D may comprise
a base container 301 and a compartmentalized basket-tray 302. The
basket-tray 302 may include a plurality of compartments 310, each
containing one or more distinct food components. Each compartment
310 may include perforations 311 allowing the transfer of the
vapor-phase of a liquid component disposed in the base container
301 into the individual compartments 310. Such a configuration
provides a mechanism whereby the food component disposed in each
compartment 310 may be directly adjacent to the liquid component in
the base tray and may receive the full effects of the vapor-phase
interaction.
[0158] As previously described the size and shape of the
perforations 311 may be adjusted so as to optimize the amount of
interaction between the vapor-phase of the liquid component and the
remaining food components disposed in the respective compartments
310. It should also be noted that one or more of the compartments
310E may be either substantially or completely free of perforations
so as to inhibit or prohibit the interaction between the vapor
phase of the liquid component and the food components disposed
within such perforation-free compartments.
[0159] Referring to FIG. 33, a cooking apparatus 300E may comprise
a base container 312 having a plurality of compartments 313 and a
plurality of basket trays 314 and non-perforated trays (not shown)
which may be received within the compartments 313. Such a
configuration allows for the use of one or more liquid components
which may be independently disposed within the various compartments
313. As such, various solid food components 315 may be contacted
with vapor-phases of distinct liquid components thereby providing
for the optimization of the cooking and flavoring characteristics
for each component 315. Additionally, the final moisture content of
a specific solid food component 315 may be specifically tailored by
controlling the amount of liquid component.
[0160] Similarly, FIG. 34 presents a cooking apparatus 300F where
distinct food components 316 and their associated liquid components
may be maintained in separable containers 317. Each separable
container 317 may comprise a base container 318 and a basket-tray
319 or non-perforated tray 319 which may be received in the base
container 318. The apparatus 300 may also comprise means 320 for
separating the separable containers 317. Such means may include
perforations, score lines, tear tabs, or any other such mechanism
common to the art. Such a configuration provides the benefits of
the multiple-compartment/multiple liquid arrangement detailed with
respect to FIG. 33. Additionally, the separable containers 317 may
allow for the varied cooking characteristics of specific food
types. The separable nature of the apparatus 300 allows for
differing cook times to be realized for differing food types
thereby optimizing the characteristics of the finally prepared food
product 316. The separable nature of the apparatus 300F also
provides a mechanism whereby a given liquid component disposed in a
base container 318 may be further utilized as a component of the
meal as it can be independently plated on or about a given food
component 316 due to the ease of pouring or otherwise removing the
liquid component from a base container 317A which may have been
individually separated from other base containers 3178.
[0161] FIG. 35 presents a cooking apparatus 300G, similar to that
presented in FIG. 34. Cooking apparatus 300G may comprise a base
container 321 having a plurality of compartments 322, a plurality
of secondary tub containers 323, and a plurality of basket-trays
324. The basket-trays 324 may be received in the secondary tub
containers 323, which may then be received within a given
compartment 322 of the base container 321. As with the separable
base containers 317 of FIG. 34, the incorporation of the secondary
tub containers 323 allows for the use of one or more distinct
liquid components which may be independently disposed within the
various secondary tub containers 323. Such a product also provides
a simplified mechanism for separating various food components 325
for independent preparation whereby the secondary tub container 323
and basket-tray 324 containing each food component may simply be
removed from the base container 321. Similarly, a basket-tray 324
may be omitted from a secondary tub container 323 so as to provide
a simple tray container for food items for which steam cooking is
not desired.
[0162] As previously described, the cooking apparatuses generally
comprise base containers which may hold a liquid component, such as
liquids, gels, partially liquid or gelatinous mixtures, and
mixtures thereof as a single mass maintained in a frozen condition
which, upon heating, generates a vapor-phase which facilitates the
cooking and/or flavoring of various other solid food components.
The cooking apparatus may also comprise additional formulations and
structures for the liquid component.
[0163] Referring to FIG. 36A a cooking apparatus may be comprise
liquid component may be in a particulated formulation. Such
particulates may include granules 401, flakes or chips 402,
shavings 403, or chunks or cubes 404. The various particulate
formulations provide numerous advantages including more efficient
thawing and heating of the food components due to the increased
surface-area:volume ratio and corresponding decrease in density.
Such characteristics result in shorter cook times, thereby causing
less thermal degradation of the food components due to heating.
[0164] The liquid component may be initially disposed in a frozen
block or particulated 401-404 form atop the solid food components
(not shown) such that, upon heating, the liquid component may melt
and flow downward over the solid food items to create a braising
effect for the solid food items.
[0165] As shown in FIG. 36B, solid food pieces 405 comprising
portions of protein, vegetable, starch or other food types may be
incorporated into the liquid component 406. Such incorporation
provides for more direct flavor transfer between the liquid
component 406 and the solid food component pieces 405. Also, such
incorporation may remove the need for subsequent mixing steps for
particular liquid component/solid component combinations which may
be commonly preferred to be consumed together (e.g. pasta and
sauce). Additionally, the disposition of solid food component
pieces 405 which may be susceptible to freezer burn within the
liquid component 406 may serve to reduce or eliminate such
effects.
[0166] Referring to FIG. 37, a liquid component 501 may be disposed
within pouch 502. The pouch 502 may be frangible or dissolvable
upon heating or may be removable such that a user may open the
pouch so as to dispense some or all of the liquid component 501
into the base container 503 prior to, during or after cooking. Such
a pouch would allow for the use of a liquid component in
combination with frozen, refrigerated or shelf-stable solid food
components while still providing the benefits of the vapor-phase
cooking capabilities of the apparatus, as previously described. The
pouch 502 may be constructed so as to rupture due to a buildup of
pressure within the pouch 502. Alternately, the pouch 502 may be
dissolvable or edible and may be constructed from materials
including starch, cellulose, or protein based components.
Similarly, the base container 503 and/or the tray 504 may be
constructed from edible materials including starch, cellulose,
protein based components, food stuffs including tapioca, bamboo,
potato, and pastries. The edible tray materials may further
comprise various flavoring additives.
[0167] The liquid component may be formulated as a dehydrated or
partially dehydrated composition, or as a powdered mix. Such
formulations may provide numerous benefits. Maintaining the liquid
component in a dehydrated or dry formulation may reduce or
eliminate the need for full hermetic sealing of the cooking
apparatus due to the shelf-stable or semi-shelf-stable nature of
the dehydrated food component so that the cooking apparatus could
be utilized in combination with refrigerated or shelf-stable solid
food components.
[0168] Additionally, common practices in the art utilize blast
freezing to freeze liquid components. Prior to its freezing, a
liquid component may be introduced into a cooking apparatus at
temperatures above its freezing point so that it may be
conveniently poured into the apparatus. However, solid food
components which may have already been individually quick frozen
(IQF) and disposed within the apparatus may be partially thawed due
to their exposure to the warmer liquid component. Such freezing and
thawing may cause degradation of the cell structures of certain
solid components resulting in negative taste and/or textural
characteristics. Further such blast freezing steps may be both time
and energy intensive. The use of dehydrated or partially dehydrated
liquid components would eliminate the need for blast freezing steps
in the production of components used in the cooking apparatus. The
removal of moisture from the liquid component would also result in
a lighter overall product thereby lowering production and shipping
costs.
[0169] Referring to FIG. 38, a liquid component 601 may be
formulated as a dehydrated powder or granular composition.
Referring to FIG. 39, a liquid component may be formulated as a
dehydrated matrix 602 where a binding agent may be incorporated to
maintain the component in a singular complex which may be formed as
strips, pieces or leathers. Such binding agents may include gums,
starches or other binders known by those knowledgeable in the art.
Referring to FIG. 40, a liquid component may be formulated as a
partially hydrated composition 603, such as a gel, concentrate or
paste. Such a formulation may be desirable where rehydration of a
fully dehydrated liquid component may be impractical due to timing
considerations.
[0170] Should a dehydrated liquid component be incorporated into a
cooking apparatus 600, a mechanism for rehydrating the component
would necessarily be required. Various rehydration mechanisms are
presented in FIGS. 41-46.
[0171] FIG. 41 presents a cooking apparatus having a dehydrated
liquid component 604 disposed within a base container 605. A layer
or block of frozen liquid 606 may be disposed along the floor of an
upper basket-tray 607. Upon heating, the frozen liquid 606 will
melt and flow through the basket-tray perforations 608 and contact
the dehydrated liquid component 604, thereby allowing for the steam
cooking of the solid food components 609 contained in the
basket-tray 607 via a rehydrated liquid component 604.
[0172] Similarly, FIG. 42 presents a plurality of solid food
components 610 on which a frozen liquid glaze 611 may have been
disposed. Upon heating, the frozen liquid glaze 610 will melt and
flow through the basket-tray perforations 608 and contact the
dehydrated liquid component 604, thereby allowing for the steam
cooking of the solid food components 610 contained in the
basket-tray 607 via the rehydrated liquid component 604.
[0173] FIG. 43 presents a frangible or dissolvable
liquid-containing pouch 612 which may be either adhered to a lid
structure 613 which encloses the apparatus 600F or simply disposed
atop a plurality of solid food components 614. Such a configuration
allows a heated liquid to flow over the solid food components 614,
thereby permitting rapid initiation of the steaming process. The
liquid may then flow through the apertures 615 in the basket-tray
616 to contact the dehydrated liquid component 617 disposed within
the base container 618 thereby rehydrating the liquid component
617.
[0174] Similarly, FIG. 44 presents a similar configuration where
the frangible or dissolvable liquid-containing pouch 612 may be
disposed substantially adjacent to the underside of the basket-tray
616. Such a configuration ensures that a desired amount of liquid
612 may be contacted with the dehydrated liquid component 617 and
may be not entrained within the solid food components 614.
[0175] It may also be desirable for the consumer or end-user to add
the liquid required to rehydrate a dehydrated liquid component.
Such a configuration may have several inherent benefits over frozen
liquid components. For example, the cost of adding the liquid may
be saved. Further, because less liquid may be contained in the food
product, the overall weight of the food product may be reduced
decreasing the cost of shipping the food product. Also, if the
solid food components may be frozen, utilization of a dehydrated
liquid component will decrease cooking time as the liquid component
will not need to be thawed. Additionally, pre-heated liquids may be
used as the rehydration medium so as to further reduce the cook
time. Further, if the product may be to be frozen, the sauce will
not have to be selected from sauces with lower freezing points so
as to prevent the sauce from thawing prematurely and creeping into
unintended areas.
[0176] Furthermore, partially dehydrated and fully dehydrated
liquid components may not require pre-cooking as may be the case
with hydrated liquid components. Therefore, the rehydrated liquid
component will be fresher and taste better when it may be cooked
for the first time by the consumer.
[0177] Also, the consumer or end-user may be permitted to vary the
rehydrating liquid so as to customize the resulting liquid
component to their particular tastes. The liquid may be any edible
liquid, such as dairy based liquids (i.e. milk or cream), alcoholic
beverages (i.e. beer or wine), meat stocks or broths, oils, sodas,
waters, juices, and the like.
[0178] Referring to FIGS. 45A and 45B a cooking apparatus 700A may
comprise a base container 701 and a basket-tray 702. The perimeter
wall of the basket-tray 702 may comprise an indention 703 along one
side. The indention 703, together with the base container 701, may
provide a conduit 704 whereby a rehydrating liquid 705 may be
transmitted into the interior of the base container 701. Such a
configuration provides for direct routing of the rehydrating liquid
705 to the dehydrated liquid component where the flowable
characteristics of the rehydrating liquid 705 may serve to create a
zone of turbulence thereby enhancing the rehydration process.
[0179] Referring to FIG. 46A, a cooking apparatus 700B may comprise
a base container 706 and a plurality of basket-trays 707 which may
be removably received within the base container 706. The base tray
706 may contain a dehydrated liquid component (not shown). In order
to rehydrate the dehydrated liquid component, a rehydrating liquid
708 may be poured into the basket-trays 707. The liquid 708 may
interact with the solid food components 709 as it flows downward
through basket-trays 707 and into the base container 706 where it
may rehydrate the dehydrated liquid component. This interaction
between the liquid 708 and the solid food components 709 may serve
to initiate thawing or pre-cooking of the solid food components
depending on the temperature of the liquid 708. Such thawing or
pre-cooking may serve to further shorten the cook time for the
solid food components 709.
[0180] A cooking apparatus 700B, may comprise a resealable lid
structure 710 having cooperating resealing means 711. Such
resealing means 711 may comprise a complementary tooth and grove
system, a zipper seal, resealable adhesives, snap-on connections,
and the like. Such configurations may be beneficial when a complete
seal about the entirety of the apparatus 700B may be desired.
[0181] Similarly, as presented in FIG. 46B, the cooking apparatus
700C may comprise a sealed cover 712 having a releasable portion
713 which may be resealed by an interlocking tab 714 and slot 715.
Such a configuration may be used when complete resealing may be not
required. Additionally, the sealed cover 712 (and releasable
portion thereof 713) may further comprise venting apertures 716.
Such apertures 716 may allow for the release of a portion of the
built up pressure within the apparatus 700C during cooking so as to
avoid displacing the cover 712. Further, as presented in FIB. 46C,
a resealable lid structure 717 may comprise a lip portion 718 which
may cooperatively engage the flanged portions 719 of the base
container and basket-trays 720.
[0182] It may be desirable to provide a cooking apparatus 800 which
may allow for the pressure generated by the heating of the food
components (particularly the liquid component) to be either vented
or maintained so as to optimize the cooking characteristics of the
food components.
[0183] Referring to FIG. 47, a cooking apparatus 800 having a
pressure release mechanism is presented. A cooking apparatus 800
may comprise a base container 801 and a basket-tray 802. A lid
structure 803 may be disposed about the top of the apparatus 800 so
as to enclose the food components 804 contained within. The lid
structure 803 may be sealed about the flanged portions 805 of the
base container 801 and the basket-tray 802 via mechanical or
adhesive means. Additionally, substantially unsealed portions 806
may be disposed about the perimeter of the lid structure 803. The
substantially unsealed portions 806 may provide a conduit for some
or all of the expanding vapor generated by the heating of the food
components 804 to be released into the atmosphere. The size and
shape of the substantially unsealed portions 806 may be configured
so as to regulate the amount of pressure which may be released so
that overpressures may be maintained without risk of rupture.
[0184] The substantially unsealed portion 806 may comprise
sufficient sealing strength so as to maintain a complete seal for a
period of time, thereby enabling pressure cooking of the food
components 804, but which will vent at a given time, temperature or
internal pressure so as to provide for further vented cooking.
[0185] The apparatus 800 may comprise one-way or two-way valves or
vents (not shown) as the pressure release mechanism. Such
mechanisms may allow for more precise maintenance of the pressure
levels within the apparatus. Other self-venting or controlled
venting mechanisms which may be commonly known in the art may also
be incorporated in the cooking apparatus 800.
[0186] A sealable cooking apparatus 800 may be vacuum sealed or
flushed with non-oxidative gasses, such as nitrogen, so as to
prevent the oxidation and/or degradation of the food components,
thereby extending the shelf-life of the food components 804.
[0187] Furthermore, any of the cooking apparatuses described herein
may be disposed within a film overwrap, such as those disclosed in
U.S. patent application Ser. No. 11/636,260, herein incorporated by
reference. Referring to FIG. 48, a cooking apparatus 900 may
comprise a base container 901 and one or more basket-trays 902
disposed within a non-venting film overwrap 903. The film overwrap
903 may comprise a nylon blend, polymers, heat sealable papers,
cellophane, foils and the like, having selected physical properties
such that it may maintain a closed cooking environment in both
microwave and radiant-heat cooking environments. In order to be
non-venting, the film overwrap 903 may be capable of maintaining an
internal cooking environment that remains separated from the
ambient environment during the cooking process.
[0188] The non-venting film overwrap 903 may have one or more of
the following properties: [0189] Heat deflection temperature (66
psi): at least 400.degree. F. [0190] Heat deflection temperature
(264 psi): at least 160.degree. F. [0191] Melting point: at least
420.degree. F. [0192] Elongation fail percentage: 150-170% Such
film overwraps may include those produced by the KNF
Corporation.
[0193] Such properties may enable the film overwrap 903 to expand
to a certain degree under heating while maintaining its structural
integrity and avoiding rupture. This allows the cooking apparatus
900 to maintain the sealed, non-venting environment in which the
temperature and pressure can be increased during the cooking
process. Such capabilities may provide for the pressure cooking of
the food items 904. Because water's boiling point increases as the
surrounding air pressure increases, the pressure built up inside
the food packaging allows the liquid in the packaging to rise to a
temperature higher than 212.degree. F. before boiling, thereby
providing elevated cooking temperatures resulting in reduced cook
times.
[0194] The film overwrap 903 may be a heat-releasable or
pressure-releasable film overwrap where the interior of the
overwrap remains sealed until heating begins. The film overwrap may
be constructed of plastics, polymers, heat sealable papers,
cellophane, foils and the like.
[0195] Similarly, one or more individual food components disposed
within various basket trays or tray compartments may also be
enclosed within separate venting or non-venting cooking bags so as
to produce specified cook characteristics such as pressure cooking,
steam cooking, and the like. The material of the cooking bags may
comprise nylon; Polyethylene Terepthalate (PET); PP; EVOH;
polyurethane; formed, opened, or closed cellulose structures;
combinations, blends or laminations thereof, and the like.
[0196] Referring to FIGS. 49A and 49B, a cooking apparatus 1000 may
include at least first 1002 and second 1004 substantially coplanar
compartments wherein food components and a liquid component may be
maintained in spatial separation so as to avoid their commingling
during storage or cooking. The cooking apparatus 1000 may comprise
a base container 1001 having at least a first compartment 1002
containing a liquid food component 1003 and a second compartment
1004 containing at least one solid food component 1005.
[0197] Referring to FIG. 49A, the cooking apparatus 1000A may
further comprise a partition maintained in spatial separation 1007
from a lid structure 1008. The spatial separation 1007 may provide
a pathway for the transfer of the vapor-phase portion of the liquid
component 1003 into the second compartment 1004 to facilitate the
steam cooking and flavoring of the solid food components 1005, as
has been previously discussed. Additionally, a removable or
collapsible partition portion, such as a tear away strip or hinged
projection (not shown) may be incorporated so as to completely
separate the first compartment 1002 and the second compartment 1003
during shipping and storage so as to prevent the commingling of the
liquid component 1003 and the solid components 1005 until the
cooking apparatus 1000A may be ready for use.
[0198] Additionally, the apparatus 1000A may comprise a
condensation absorption mechanism. Particularly, the second
compartment may comprise a liquid absorbing insert 1011 constructed
of or coated with a moisture absorbing coating, such as
polypropylene, cellulose, silica or foam based materials so as to
prevent the solid food components 1005 from sitting in any
condensate generated during cooking. Alternately, the portion of
the base container 1001 comprising the second compartment 1004 may,
itself, be constructed of like moisture absorbing materials.
[0199] Referring to FIG. 49B, a cooking apparatus 1000B may
comprise a screen 1009 having a plurality of perforations 1010
which may be disposed between the first compartment 1002 and the
second compartment 1004 thereby permitting the transfer of steam or
other vapor-phase components between the respective
compartments.
[0200] Additionally, the cooking apparatus 1000B may comprise a
second compartment 1004 having an inclined floor 1014 so as to
direct any condensed liquid back through the screen 1009 and into
the liquid component 1003. The inclined floor 1014 may include
channels (not shown) directed down the slope of the incline or a
plurality of raised knobs (not shown) thereon to elevate the solid
food components 1005 above the flow paths for any condensed liquid
so as to facilitate the transfer of the condensed liquid from the
second compartment 1004 back to the first compartment 1002. Such a
configuration ensures that any nutrients which may leach out of the
solid food components 1005 during cooking may be retained within
the liquid food component 1003 so that the consumption of the solid
food components 1005 and the liquid component 1003 ensures that all
nutrients present in the original components may be preserved.
[0201] Additionally, there may be currently a limited number of
materials that may be viable for dual ovenable cooking (i.e.
suitable for use in both conventional ovens and microwave ovens).
Such materials include crystalline polyethylene terephthalate
(CPET), amorphous polyethylene terephthalate (APET)/CPET
composites, and nylon/CPET composites. These materials may be
acceptable for dual ovenability due to their high melting point and
glass transition points.
[0202] However, certain limitations exist with respect to these
materials. Typically, these materials must to be thermoformed and
may be not capable of being formed through injection molding. This
limits the size and variety of shapes available. Additionally,
perforations can not be created in these materials in a tray format
without adding a secondary cutting operation, which adds potential
quality and food safety may besues (e.g. hangers, slivers, missed
punches, etc). Containers constructed from these materials may also
have highly crystalline structures making them fragile and prone to
breakage upon forceful contact. It may also difficult to create and
maintain hermetic seals to these materials.
[0203] Conversely, in dual-ovenable constructions, other
traditional packaging materials, such as polypropylene (PP),
high-density polyethylene (HDPE), and low-density (LDPE), may be
not capable of withstanding the high temperatures of ovens due to
their lower melting and glass transition points. For example, PP
melts at roughly 350.degree. F. However, these traditional
materials may be capable of accounting for the shortcomings of
CPET, APET/CPET, and nylon with respect to their thermoforming,
perforation, and durability may besues.
[0204] Currently, foods packaged in a trays may be generally
single-tray configurations (for all frozen, refrigerated, and shelf
stable products) which requires that the single-tray must be able
to withstand the full temperature of the oven. A solution to
solving this may besue may be to utilize food components disposed
within progressively removably received trays thereby providing
thermal insulation for the internal trays.
[0205] Referring to FIG. 50, an outer base container 1101 may be
manufactured from current dual ovenable materials (e.g. CPET,
nylon, CPET/APET, etc). The base container 1101 may contain a food
component 1102 which may be either a liquid component or a solid
component. At least one inner basket-tray 1103 may be disposed
within the base container 1101 and contain additional food
components 1104. The full free spaces defined by the base container
1101 and basket-trays 1103 would be filled with food components
1102, 1104 including the vertically directed portions defined by
the side walls of the base container 1101 and basket-trays 1103. As
such, the food components 1102, 1104 may act as insulating layers
around the entirety of each basket-tray 1103.
[0206] Typical finished cook temperatures of most food products may
be approximately 165-185.degree. F., with a fail-safe at
212.degree. F. when the water in a water-containing component 1102,
1104 would begin to boil, thereby maintaining that temperature
until the water was fully evaporated.
[0207] In such a configuration, the basket-trays 1103 could be
manufactured from materials which can withstand temperatures of
approximately 212.degree. F. As such, numerous other material
including PP (melting point at 348.5 deg F.), polyethylene (melting
point of 278 deg F.), Poly(l-butene) (melting point of 270 deg F.),
and others may be utilized in dual-ovenable constructions. Use of
these materials would allow the basket-trays 1103 to be injection
molded, allowing for a greater variety of shapes and features
(including perforations or holes that may be made in-mold), greater
shock resistance, and a much lower cost for the inner tray than if
previously made from standard dual ovenable materials.
[0208] The presently disclosed cooking apparatus may have numerous
advantages over the prior art by separating the different types of
food components. This separation leads to significant improvements
in food quality, including improvements in texture, hold life,
color, and flavor.
[0209] First, the separate cooking produces a food product that may
be plateable. Plateability allows the consumer to choose between
different food items and/or sauces that may be cooked
simultaneously. Therefore, an individual may plate, assemble, and
customize their meal according to his or her preferences and
tastes. Moreover, plateability allows food to be placed on a plate
or tray in different visually appealing configurations. Further, if
an individual may be allowed to plate his or her own meal, the
cooking apparatus allows each individual to sort out unhealthy
items if desired.
[0210] Second, the cooking apparatus provides several thermodynamic
advantages in cooking by separating the different types of food
components to create a more appetizing and higher quality food
product. Separating the food components increases the surface area
of the food components by total volume. The increased surface area
increases the surface area to which heat may be transferred
resulting in greater efficiency in cooking. Further, the thickness
of the food components may be decreased, allowing for shorter
cooking times and more even cooking.
[0211] Moreover, the density of the food components may be
decreased allowing the heating apparatus (e.g., microwave oven,
convection oven, and the like) greater access to the center of the
food component for better and faster cooking times. Additionally,
the food components may be not as densely packed, allowing the food
component to be more effectively heated with better heat transfer
also helping to shorten cooking times. Typically, the less cooking
time utilized, the less heat degradation of the food product.
[0212] Furthermore, the cooking apparatus may be compartmentalized
to allow food components that require that require varying amounts
of thermal energy for cooking to be properly heated so as to
prevent undercooking and/or overcooking of a food component.
Individual compartments may comprise varying degrees of insulation
so as to provide appropriate levels thermal energy transfer to a
given food component.
[0213] Third, the cooking apparatus provides several storage
advantages by separating the different types of food components to
produce a more appetizing and higher quality food product. The
separation of food components may help to prevent degradation and
discoloration during storage from the interaction of differing
types of food components. Further, separation of food components in
multiple compartments may help to prevent freezer burn when the
cooking apparatus may be stored in a freezer.
[0214] Fourth, the cooking apparatus provides several processing
advantages by separating the different types of food components to
produce a more appetizing and higher quality food product. The
separate trays or compartments allow different types of food
components to be manufactured, frozen, and/or processed,
separately. Differing types of food components may require
different processing, manufacturing, and freezing conditions and
the conditions required for one food component may have negative
effects on the quality of another food component by effecting
texture, color, and the flavor of the food component. Therefore, by
separating the differing types of food components, each type of
foodstuff may get the exact amount of freezing, processing, and
manufacturing required producing a better tasting and higher
quality food product.
[0215] Fifth, the separation of the different types of food
components also provides decreased freeze times for products that
may be freezer stored. The reduced density and increased surface
area of the food components provided by the separation of the
different types of food components makes the food components freeze
faster. The decrease in freeze time reduces overall processing
requirements and increases the efficiency of producing the product.
An increase of efficiency reduces the cost of making the freezer
stored product.
[0216] It may be believed that the above description may be further
understood by the following examples, which may be not limiting in
any way.
Example 1: Chicken Primavera
[0217] Two samples of Chicken Primavera were prepared under the
same conditions to look for improvement in food quality and cook
times. The first sample was prepared according to current methods
using an aluminum tray and a frozen block of the Chicken Primavera
with all ingredients mixed together. The second sample was prepared
using a foodservice compatible ovenable cooking apparatus 220,
which included an aluminum basket 222 with openings 238 removably
received within an aluminum container 224. The container 224
included a medium depth tray pan and contained sauce. The basket
222 was a shallow tray pan with between 20 and 40 oval shaped
openings 238 approximately 1'' long. The basket 222 was removably
received within the container 224 and contained vegetables and
proteins. The size of the basket 222, container 224, and the amount
of sauce allowed for an air gap between the base 240 of the basket
222 and the sauce.
[0218] Significant improvements were observed in comparisons
between the conventional method and the ovenable cooking apparatus
220. The sample prepared using the ovenable cooking apparatus 220
resulted in huge improvements in product quality, including
improved sauce color and impoved vegetable texture, color, and
flavor.
Example 2: Beef Stew
[0219] Two samples of Beef Stew were prepared under the same
conditions to look for improvement in food quality and hold life.
The first sample was prepared according to current methods using an
aluminum tray and a frozen block of the Beef Stew with all
ingredients mixed together. The second sample was prepared using a
foodservice compatible ovenable cooking apparatus 220, which
included an aluminum basket 222 with openings 238 removably
received within an aluminum container 224. The container 224
included a medium depth tray pan and contained sauce. The basket
222 was a shallow tray pan with between 20 and 40 oval shaped
openings 238 approximately 1'' long. The basket 222 was removably
received within the container 224 and contained vegetables and
proteins. The size of the basket 222, container 224, and the amount
of sauce allowed for an air gap between the base 240 of the basket
222 and the sauce. The products were sampled after preparation, 30
minutes later, 60 minutes later, and 90 minutes later to compare
their quality under conditions where they may be kept warm for
serving after being cooked (their hold life).
[0220] Significant improvements were observed in comparisons
between the conventional method and the ovenable cooking apparatus
220. The sample prepared using the ovenable cooking apparatus 220
resulted in huge improvements in product quality, including
improved sauce color and impoved vegetable texture, color, and
flavor. The potatoes and carrots prepared using the ovenable
cooking apparatus 220 were significantly better than the potatoes
and carrots prepared using conventional methods. The beef also
showed superior quality over time compared to the beef that was
prepared conventionally.
Example 3: Chicken Parmigiana
[0221] A first sample of chicken parmigiana was prepared according
to the conventional method, which included a frozen block of all
ingredients in a foodservice tray. A second sample of chicken
parmigiana was prepared using the ovenable cooking apparatus. The
sauce was placed in the container and the chicken parmigiana and
pasta were placed in the basket and cooked. The basket did not
include openings for steam to enter the basket.
[0222] There were significant improvements in the sample prepared
using the ovenable cooking apparatus. The chicken from the first
sample was soggy and did not meet consumer standards. The chicken
from the ovenable cooking apparatus had the appropriate crispy
texture. The pasta also had improved texture and flavor.
Example 4: Tandoori Chicken
[0223] Tandoori Chicken was prepared using the ovenable cooking
apparatus 220, which included an aluminum basket 222 removably
received within an aluminum container 224. The basket 222 did not
include perforations. The basket 222 contained 30 ounces of minted
couscous with garbanzo beans. The container 224 contained 25 ounces
of curry sauce and 30 ounces of Tandoori chicken breast in 1''
chunks.
[0224] Significant improvements were observed compared to Tandoori
Chicken prepared using a single tray and a frozen block of all
Tandoori Chicken ingredients mixed together. There were particular
improvements to sauce color and vegetable texture, color, and
flavor.
Example 5: Jerk Chicken
[0225] Jerk Chicken was prepared using the ovenable cooking
apparatus 220, which included an aluminum basket 222 removably
received within an aluminum container 224. The basket 222 did not
include perforations. The basket 222 contained 30 ounces of protein
and 30 ounces of white rice. The container 224 contained 40 ounces
of black beans and sauce.
[0226] Significant improvements were observed compared to Jerk
Chicken prepared using a single tray and a frozen block of all the
Jerk Chicken ingredients mixed together. There were particular
improvements to sauce color and vegetable texture, color, and
flavor.
Example 6: Chicken Milanese
[0227] Chicken Milanese was prepared using the ovenable cooking
apparatus 220, which included an aluminum basket 222 and an
aluminum container 224. The basket 222 did not include
perforations. The basket 222 contained 20 ounces of Chicken
Milanese, which included 10 chicken breast tenders. The container
224 contained 20 ounces of broccoli rabe and 30 ounces of mushroom
risotto. The container 224 was covered and steamed for 1 hour. The
chicken Milanese in the basket was reheated in a 350 degree oven
for 15 minutes.
[0228] Significant improvements were observed compared to chicken
Milanese prepared using a single tray and a frozen block of all the
chicken milanese ingredients mixed together. There were particular
improvements to sauce color and vegetable texture, color, and
flavor.
Example 7: Vegetarian Pad Thai
[0229] Vegetarian Pad Thai was prepared using the ovenable cooking
apparatus 220, which included an aluminum basket 222 and an
aluminum container 224. The basket 222 did not include
perforations. The basket 222 contained 30 ounces of rice flour
vermicelli and 12 ounces of vegetables, including julienne carrots,
bean sprouts, and green onions. The container 224 contained 30
ounces of sietan (wheat gluten) and 25 ounces of Pad Thai sauce.
The container 224 was covered and steamed for 1 hour. The basket
was covered and steamed for 20 minutes.
[0230] Significant improvements were observed compared to
Vegetarian Pad Thai prepared using a single tray and a frozen block
without separating the ingredients. There were particular
improvements to vegetable texture, color, and flavor, as well as
sauce color.
Example 8: Dim Sum Party Pack
[0231] A Dim Sum Party Pack was prepared using the ovenable cooking
apparatus 220, which included an aluminum basket 222 and an
aluminum container 224. The basket 222 did not include
perforations. The basket 222 contained 6 boa buns with asian
barbeque pork, 6 LaChoy Chicken Potstickers, and 6 steamed
vegetable spring rolls. The container 224 contained 12 ounces of
teriyaki sauce. The container 224 was heated for 15 minutes in a
350 degree oven while covered. The basket was steamed uncovered for
10 minutes.
[0232] The Dim Sum Party Pack was not compared to a Dim Sum Party
Pack prepared using the conventional single tray method because
this type of meal may be cannot be prepared according to
traditional methods due to the breaded ingredients. However, use of
the ovenable cooking apparatus 220 to prepare the Dim Sum Party
Pack resulted in a very high quality result, with no sogginess in
the breaded ingredients.
[0233] The presently disclosed apparatus and methods provides
numerous advantages over prior art. First, use of the container to
hold the liquid component and the basket to hold the second food
component provides separation of the food ingredients during
cooking. This may lead to significant improvements in food quality,
including improvement in texture, hold life, color, and flavor.
Separation of the food ingredients also provides enhanced control
of the moisture levels and ultimately, the quality of the food
ingredients. Individually quick frozen (IQF) foods may be placed in
the basket and may be separated from other food ingredients. As the
IQF foods thaw, moisture can drain from the basket into the
container. This keeps the IQF foods from becoming soggy from excess
moisture, and also ensures that the other food ingredients in the
container do not dry out.
[0234] Second, the apparatus and methods may allow the introduction
of new food items into the foodservice industry. Currently, breaded
items may not meet consumer standards when prepared in foodservice
trays that do not provide separation of ingredients. By placing
breaded items in the basket of the ovenable cooking apparatus, they
may come out crispy instead of soggy. This will open up a plethora
of new food items for the foodservice industry without excessive
changes to current methods.
[0235] Third, apparatus and method may also provide significant
thermodynamic and heat transfer advantages. Separating the food
ingredients increases the surface area to volume ratio, which
increases the surface area to which heat may be transferred. This
may result in greater efficiency in cooking.
[0236] Fourth, the apparatus may be largely compatible with
existing methods of meal preparation in the foodservice industry.
By nesting the basket in the container during packaging and
cooking, there may be no need for additional oven space to prepare
the meal.
[0237] Last, the ovenable cooking apparatus may allow users to
plate, assemble, and customize their meal according to their
preferences and taste. The presentation of the meal may be more
attractive and appealing when consumers can choose how to place
each component and how much of each food ingredient they would like
to put on their plate. By keeping the food components separate
during cooking, the ingredients don't intermix and consumers can
customize their meals with varying amounts of ingredients.
[0238] It may be believed that cooking apparatuses and methods and
many of their attendant advantages will be understood by the
foregoing description, and it will be apparent that various changes
may be made in the form, construction and arrangement of the
components thereof without departing from the scope and spirit of
the above description or without sacrificing all of its material
advantages. The form herein before described being merely an
explanatory representation thereof, it may be the intention of the
following claims to encompass and include such changes.
