Abstract

A system for controlling energization of an electrical resistance heater disposed in heat exchanging relation with a food cooking medium includes a signal generator providing an output signal of amplitude-time character defining a preselected cooking cycle, an element in the cooking medium providing a control signal indicative of cooking medium temperature and circuitry interconnecting an electrical voltage supply with the heater for excitation thereof responsively to both the control signal and the signal generator output signal.
