In an automatic popcorn popper, a thermostat senses the temperature drop of the cooking kettle at the time that the kettle is supplied with corn and seasoning. The temperature will decrease to a predetermined level or below if the proper quantities of corn and seasoning are supplied. Depletion of either ingredient will be sensed since the temperature will fail to decrease to such level, whereupon automatic shutoff of the popper is effected and an alarm signal is produced. A high temperature thermostat also effects shutoff if, during cooking, the kettle reaches a temperature indicative of overheating of the product.
