The apparatus includes a compressible, heat-resistant ring member, and optionally a flexible, non-stick, heat-resistant film material associated with the ring member to form a cavity defined by the inner perimeter of the ring member. A cooking method is also disclosed, wherein a food item and a quantity of water are introduced into the cavity, and the food item is simultaneously cooked by the heated upper and lower platens of a conventional clamshell grill or similar apparatus and by steam generated by heating the water. ## Claims ### Claim 1 An apparatus for cooking a solid food item having a non-uniform thickness on two sides of the food item simultaneously with a two-sided grill, comprising: a vertically compressible, heat-resistant ring member, a two-sided grill comprising a lower platen and an upper platen, the heat-resistant ring member for being removably placed between the upper and lower platens of the two-sided grill to form a cavity sufficient to contain a food item to be cooked on the two-sided grill within an inner perimeter of the ring member and between the upper and lower platens, the cavity having a height approximately equal to an uncompressed height of the ring member, the height of the cavity contracting to a compressed height of the ring member when the ring member is compressed by the platens, the ring member being compressible to a height of about 90% or less of the uncompressed height of the ring member when the ring member is subjected to a compression force of 2 pounds per square inch, and a flexible, non-stick, heat-resistant thin film material separate from and for being located under the ring member to form a cavity within the inner perimeter of the ring member between the upper platen and the film material, wherein the cavity is adapted to hold water, and so that when the food item is placed within the inner perimeter of the ring member, the food item is in direct contact with the film material over the lower platen and the film material is in direct contact with the heated lower platen. ### Claim 2 (depends on 1) The apparatus of claim 1, further comprising a flexible, non-stick, heat-resistant film material located above and below and covering the ring member separate from and associated with the ring member to form a cavity within the inner perimeter of the ring member. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the film material is a single sheet and the single sheet in conjunction with the ring member defines a cavity within the inner perimeter of the ring member. ### Claim 4 (depends on 2) The apparatus of claim 2, wherein the film material comprises an upper and lower sheet. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the lower sheet lines the cavity within the inner perimeter of the ring member. ### Claim 6 (depends on 4) The apparatus of claim 4, wherein the lower sheet defines a volume in conjunction with the ring member. ### Claim 7 (depends on 4) The apparatus of claim 4, wherein the upper sheet of film material is mounted to the heated upper platen and covers the top face of the ring member. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the film material comprises PTFE, and has a thickness of about 0.0045 inches or less. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the ring member comprises a tube of compressible, heat-resistant material disposed around a rigid core member. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the ring member comprises a tube of compressible heat-resistant material with a hollow core. ### Claim 11 (depends on 1) The apparatus of claim 1, comprising an array of vertically compressible, heat-resistant ring members. ### Claim 12 (depends on 1) The apparatus of claim 1, wherein the ring member comprises a tube of compressible, heat-resistant material disposed around a core metal ring. ### Claim 13 (depends on 1) The apparatus of claim 1, the ring member being formed from a material selected from the group consisting of a silicone rubber, a urethane rubber, and a fluoropolymer. ### Claim 14 (depends on 1) The apparatus of claim 1, the ring member being resistant to cooking temperatures up to at least about 425° F.
