<p>Device for preparing comestibles (61) with hot gaseous fluid directly in a dish (64) includes a gas-impermeable body (57), a fluid inlet (69) connected to a generator (32) for the pressurized hot gaseous fluid, a seal plate (53) around the body (57) for sealing to the top of the dish (64) to create a closed cooking chamber, a distributor having a plurality of orifices (63a-b) to convert the pressurized hot gaseous fluid into a plurality of jets to inject onto or into the comestibles (61) to cause uniform heating of the comestibles (61) in the dish. It also has an extendable member (12) for allowing the body (57) to move between a rest position and a cooking position in which the seal plate (53) and dish (64) are engaged. To improve cooking efficiency, the hot gaseous fluid is delivered to comestibles (61) in the form of pressure pulses, each comprising a pressurization period during which the hot gaseous fluid is forced into the pores in the comestibles (61) and a de-pressurization period during which the fluid is forced out of the pores.</p> |
