1. A method for operating a heating element, in particular in a food processor for at least partially automatic preparation of foodstuffs, wherein the following steps are performed:
a) detecting an electrical resistance of the heating element such that at least one resistance value is determined,
b) performing a heating operation on the heating element based on the at least one determined resistance value to perform the heating operation depending on a temperature of the heating element,
wherein the currently detected electrical resistance, which is specific for the electrical resistance of the heating element, is directly serving as a basis for the temperature-dependent heating operation.
