Abstract
The invention relates to a method for operating a heating element (210), in particular in a food processor (1) for the at least partially automatic preparation of foodstuffs, wherein the following steps are performed: a) detecting an electrical resistance of the heating element (210) such that at least one resistance value is determined, b) performing a heating operation on the heating element (210) based on the at least one determined resistance value to perform the heating operation depending on a temperature of the heating element (210).
