An automated cooking system (10) cooks food (12) accompanied by machine-readable indicia, such as a bar code (16) read by a reader (18). Cooking data, including function coefficients, are accessed from an Internet server (20) based on the information in the bar code. An oven (40) cooks the food in phases in response to the cooking data and one or more monitored food parameters of humidity, temperature and weight. The cooking is controlled by functions in which one or more food parameters are multiplied by coefficients that vary according to food type.
