A method for determining the suitability of a cookware for a corresponding induction coil of an induction cooking hob is provided. The method includes detecting current through the induction coil, detecting the phase difference between the voltage and current of the induction coil, and detecting the frequency at the induction coil. The method further includes comparing the detected current with a stored maximum value of the current, comparing the detected phase difference with a stored maximum value of the phase difference, comparing the detected frequency with a stored maximum frequency, calculating the power transfer from the detected current, phase difference and/or frequency, estimating the suitability of the cookware in dependence of the power transfer and at least one of the compared parameters, and outputting at least one optical and/or acoustic signal corresponding with the suitability of the cookware.
