Stackable cooking apparatus

A stackable cooking apparatus for cooking a food item, the stackable cooking apparatus being supportable by a heat source, the stackable cooking apparatus comprising:

• a lower vessel having at least one first sidewall and a first top wall defining a first volume therebetween, the first top wall being adapted to support the food item thereon and defining a plurality of perforations through the first top wall, the lower vessel defining a recess in an upper portion thereof, the lower vessel further having an open bottom to allow thermal energy radiated from a heat source on which the lower vessel is supported to directly heat the first volume, the open bottom opening directly onto the heat source, the heat source supporting the stackable cooking apparatus;
• and
• an upper vessel adapted to be coaxially mounted atop the lower vessel, the upper vessel having at least one second sidewall and a second top wall defining a second volume therebetween for substantially surrounding the food item supported by the first top wall, the upper vessel further including a crimped end portion defining an open bottom that opens to the second volume, the second volume being adapted to receive heat thereinto flowing along a heat transfer flow path extending from the first volume, through the plurality of perforations and into the second volume, the crimped end portion being configured for mating engagement with the recess of the lower vessel, whereby the second volume heats while the heat flows into the second volume, whereby the food item cooks while the second volume heats and whereby the upper vessel and the lower vessel are vertically connected while the crimped end portion of the upper portion matingly engages the recess of the lower vessel.

A stackable cooking apparatus for cooking a food item, the stackable cooking apparatus supportable by a heat source, the stackable cooking apparatus comprising:

• a lower vessel having a top wall having a plurality of perforations, the top wall being adapted to support the food item thereon, the lower vessel having a recess in an upper portion thereof, the lower vessel further having an open bottom to allow thermal energy radiated from a heat source on which the lower vessel is supported to directly heat a hollow interior of the lower vessel, the open bottom opening directly onto the heat source, the heat source supporting the stackable cooking apparatus;
• an intermediate vessel for cooking a food item therein, wherein the intermediate vessel includes a top wall having a plurality of perforations, the top wall of the intermediate vessel being adapted to support the food item thereon, the intermediate vessel having a recess in an upper portion thereof and a crimped portion defining an open bottom that opens to a hollow interior of the intermediate vessel, wherein the crimped portion is configured for mating engagement with the recess of the lower vessel, the intermediate vessel being adapted to receive heat thereinto flowing from the hollow interior of the lower vessel, through the plurality of perforations of the lower vessel, and into the hollow interior of the intermediate vessel, for heating the hollow interior of the intermediate vessel to cook the food item;
• and
• an upper vessel adapted to be mounted atop the lower vessel and substantially surround a further food item, the upper vessel including a crimped end portion defining an open bottom that opens to a hollow interior of the upper vessel, the upper vessel being adapted to receive heat thereinto flowing from the hollow interior of the intermediate vessel, through the plurality of perforations of the intermediate vessel, and into the hollow interior of the upper vessel to heat the hollow interior of the upper vessel for cooking the further food item, the crimped end portion of the upper vessel being configured for mating engagement with the recess of the intermediate vessel.
