1. A cooking appliance comprising:
a cooktop having at least one heating element for heating a cookware member on or to be placed on the cooktop, the at least one heating element being adjustable between a working-power level wherein the at least one heating element is energized to generate heat and a zero-power level wherein the at least one heating element is not energized;
a temperature sensor configured to detect a temperature or rate of temperature change of a cooking element; and
a control device configured to adjust the at least one heating element from the working-power level to the zero-power level when the rate of temperature change of the cooking element is equal to or above a threshold rate of temperature change, wherein the adjustment is made irrespective of the value of power presently being applied to the at least one heating element and of the present value of temperature of the cooking element.
