An automatic circuit controller for cooking food interposed between electrodes connected with a source of AC by electrical resistance in which the resistance increases until the food is cooked and rapidly declines is formed by a current switching element in series in one wire of the AC source and a current sensing element in series in another wire of the AC source. The sensed current is rectified, reduced in voltage, converted from analog to digital and applied to a microprocessor connected with the switching element for controlling the current applied to the food by delaying the time into every half cycle in response to current measuring circuitry and a zero crossing detector for triggering the switching element on. The microprocessor detects the current peak of electrical resistance of the food and stops the cooking action when the current declines to a predetermined percent of the peak.
