Abstract

A cooking utensil comprises a reading member responsive to a recording medium containing a cooking program which is carried out in the cooking utensil, and a control circuit responsive to the cooking program read by the reading member, thereby conducting the cooking program through properly energizing an energization circuit for the cooking utensil. The cooking program may be desirably recorded on the recording medium through input keys of the cooking utensil. The recorded cooking program can be checked whether or not it is recorded with accuracy. Cooking information of the cooking program is indicated by an indicator for representing conditions of the cooking utensil. The cooking program may be modified according to total weight of a foodstuff to be cooked.
