In an electric resistance cooker for quickly cooking food, such as ground meat, contactably interposed between electrodes, a food doneness control circuit is connected with the supply circuit. The control circuit senses the rate of change of the root mean square of current through the food as a function of its cooked condition and stops current to the electrodes in response to a predetermined rate of change of the root mean square value of the current through the food.
