Abstract
A food container apparatus for use in combination with a pressure cooker which enables food to be cooked with steam, while concurrently the food is browned on the upper surface thereof. The food container apparatus is received within an upwardly opening pressure cooker, with there being a boiler formed between the bottom of the food container and the bottom of the pressure cooker, and a vapor space formed between the top of the food container and the lid of the pressure cooker. An annular area is formed about the outer periphery of the food container and communicates the vapor chamber with the boiler so that steam generated at the bottom of the pressure cooker flows towards the vapor chamber in heat transfer relationship respective to the food container, and is exhausted through the pressure regulator located in the lid. A heavy heating plate at the top of the food container prevents condensation of steam from admixing with the contents thereof, and at the same time provides a heat sink. The lid is preheated to a suitable elevated temperature prior to being placed into position at the upper end of the food container, thereby providing sufficient radiant heat to brown the upper surf…
