The aim of the invention is to provide an easy to use unit which is able to reproduce cooking states in a precise manner. The unit can also be started with cold water. Several consecutive monitoring operations of cooking states should be possible without long intermediate waiting times. To achieve this, the invention provides a device for signaling at least one cooking state of at least one piece of food, such as an egg, a potato, a pepper, rice or noodles, in a liquid cooking medium (7), comprising at least one partially floating jacket (1), a temperature sensor (6a), an analog digital converter (6b), a digital computer (6) and a signal transmitter (2, 20, 21, 19). In the digital computer, the temperature value deltaa(t) of the liquid cooking medium (7) such as water is delayed with at least one thermal time constant T1, T2, T3 (15, 15a, 15b) to form a thermally delayed inner temperature value deltai(t). The temperature value deltaa(t) is measured by sensor (6a) which is provided with good thermal conductivity in relation to the jacket (1) and is digitized with the AD converter. A device (17, 18) is included in order to switch on the signal transmitter (2, 20, 21, 19) once a given first temperature threshold deltaS1 is reached, wherein a first food cooking state is signaled.
