Abstract:
1. A method of cooking foodstuff in a flow of pressurized hot inert gas in the absence of added fats using an apparatus comprising a sealable cooking chamber having a sealable opening, a gas inlet, and a gas outlet; a holder for containing the foodstuff; a gas heater coupled to a source of pressurized inert gas and to the gas inlet; a pressure sensor; a heater thermally coupled to the chamber; a pressure regulator coupled to the pressure sensor for maintaining a selected pressure within the sealable cooking chamber; a temperature sensor; a temperature controller coupled to the temperature sensor and to the heaters, comprising the steps of: a) placing a batch of foodstuff in the holder in the sealable cooking chamber; b) sealing the sealable cooking chamber; c) introducing a flow of the pressurized inert gas through the gas heater such that heated pressurized inert gas fills and pressurizes the cooking chamber to a pressure above 6 bar, a temperature in the cooking chamber being maintained between 160° C. and 360° C., flows around the foodstuff, and exits the cooking chamber through the gas outlet; d) when the foodstuff has been cooked to a desired degree, depressurizing the cooking chamber and removing the foodstuff from the cooking chamber.
