Abstract: A method and a device for detecting a boiling state of a liquid and a domestic cooking appliance permit a boiling state of a liquid to be detected during a process of heating the liquid in a heating zone, for example of an induction cooktop. A sensor senses vibrations that are caused during the heating of the liquid in the form of a measuring signal. An evaluation unit converts a time diagram of the sensed measuring signal into a frequency spectrum and then determines the boiling state of the liquid by using an intelligent algorithm on the basis of the frequency spectrum.
