Abstract
A popcorn kettle is provided with a heater plate mounting one or more heater elements in an annular configuration about a thermostat. Two semicircular disposed slots in said heater plate isolate the thermostat from heat directly conducted through the plate to the thermostat except in defined areas between ends of the slots. This prevents a high rate of heat rise which could be witnessed by the thermostat causing premature cessation of a popping cycle.
