An electrically operated food processor for preparing a cooked product, which exhibits a basic unit, a vessel with an agitator that can be inserted into the basic unit, a cooking container that sits on the vessel, a heating device allocated to the vessel, a temperature sensor, a transceiver device for communicating with the temperature sensor, and an evaluator for evaluating the measurement data received from the temperature sensor. In order to provide an electric food processor with an alternative connection between the temperature sensor and evaluator, the temperature sensor can be a surface acoustic wave sensor (SAW sensor).
