ABSTRACT:
In an automatic cooking of cake, a gas sensor and a weight sensor are used to determine a total heating time. The initial weight of a food item (cake) is measured by the weight sensor, and a time (T.sub.W) proportional to a detected value of the weight sensor is determined. The amount (.DELTA.H) of change in humidity level until an arbitrarily chosen timing is detected by the gas sensor, and a time (T.sub.(.DELTA.H)) proportional to a detected value of the gas sensor is determined. These times (T.sub.W) and (T.sub.(.DELTA.H)) are added together to determine a total cooking time. With this arrangement, regardless of the kind and amount of cake and the shape of a vessel, the automatic cooking capable of giving a fine finish can be accomplished merely by selecting a single auto-key called a cake key.
