Title: Signaling the cooking state of food cooked in pieces

Abstract: The invention provides a device for signaling a cooking state for at least one cooking item, such as an egg, a potato, a pepper, rice, noodles, that are being cooked in a liquid cooking medium. The device includes an at least partially floating jacket, a temperature sensor arranged in thermally conductive communication with the floating jacket, an analog-to-digital converter, a digital computing unit and a signaling device. The digital computing unit includes a digital delay portion to delay a temperature value of the liquid cooking medium that is measured by the sensor and digitized with the analog-to-digital converter. The delay portion has at least one thermal time constant to provide a thermally delayed inner temperature value as an output of the delay portion. A switching device is provided to activate the signaling device once a first temperature threshold is reached by the output of the delay portion, for signaling a first cooking state of the at least one cooking item.
