A method and cooktop include a cooktop panel, a cooking zone, and an induction heating device disposed below the cooktop panel. First, second and third heat sensor units are disposed beneath the cooktop panel in a region of a measuring spot. The first heat sensor unit is configured to measure heat flow from substantially only the cooktop panel. The second and third heat sensor units are configured to measure heat flow from the cooktop panel and a cooking utensil disposed thereon. A light source is provided for measuring an emissivity of the bottom of the cooking utensil. An auxiliary heater heats the region of the measuring spot. An electrical control system calculates a ratio from signals of the second and third heat sensor units and determines an actual temperature of the bottom of the cooking utensil from the ratio by using a temperature of a lower surface of the cooktop panel measured by the first sensor unit and a value of the emissivity of the cooking utensil bottom.

A method and device for determining a variation with time of an amount of steam released from a food product during a cooking process in a cooking chamber of a baking oven. A heat sink is provided outside the cooking chamber or a vapor duct in fluid communication with the cooking chamber. A sensing head of a heat conducting body projects into the cooking chamber or vapor duct, and the heat conducting body is operable to transfer heat to the heat sink. The sensing head is protected from precipitation of condensate on its surface by its spatial positioning and/or the mode of operation of the baking oven. A variation with time of the temperatures of the sensing head and cooking chamber are measured with first and second temperature sensors, respectively. The variation with time of the amount of steam in the cooking chamber is determined using an evaluation circuit of a controller as a function of measurement signals generated by the first and second temperature sensors.
