Cooking apparatus and method with product recognition

Cooking apparatus having first and second platens with product recognition. A positioning mechanism moves the second platen toward the first. A detector senses the second platen making contact with a food product disposed on the first platen and provides a signal. A controller uses the signal to measure the travel distance of the second platen. The product thickness is a function of the travel distance, which is used to select a cooking procedure for the food product. The controller then executes the selected cooking procedure to cook the food product. The detector can include a micro switch, proximity sensor, touch sensor, strain sensor, thermal sensor, optical sensor, sonar sensor or positioning load change sensor.
