Abstract
Apparatus and methods are disclosed for cooking and indicating the doneness of food products immersed in a hot liquid cooking medium such as deep hot fat. An indicator circuit that cooperates with an acoustic detector produces a first control signal indicating that acoustic activity in the cooking medium has fallen to below a threshold level for a predetermined first period of time, and afterwards produces a second control signal correlated to the doneness of the cooked food product a predetermined second period of time following said predetermined first period of time.
Claims6
A method of indicating the doneness of a food product immersed and cooked in a heated liquid oil medium comprising, the steps of;
- a) detecting acoustic activity occurring in the heated liquid medium and generating a correlated output electrical signal;
- b) detecting the amplitude of said correlated output electrical signal and generating a first control signal indicative of the correlated output signal having fallen below a predetermined threshold amplitude level continuously throughout a predetermined first period of time;
- and
- c) generating a second control signal at a predetermined second period of time following the generation of said first control signal,
- said second control signal being correlated to the doneness of the food product.
