Abstract

Abstract A computer-controller device for controlling the cooking operation of a cooking apparatus, the device having a weight input means for setting the device at a weight setting corresponding to the weight of a meat item to be cooked by the apparatus. The device has a meat doneness input means for setting the device at a doneness setting for a particular meat item. The device has means operatively associated with the input means to cause the cooking apparatus to cook the meat item at a predetermined and substantially constant cooking temperature for a period of time computed in accordance with a cooking time formula based on at least the weight setting of the device and for causing a subsequent reduction in the cooking temperature at a particular point in the time period as computed in accordance with the doneness setting of the device whereby the meat item will be substantially at the doneness of the doneness setting at the termination of the computed cooking time period.
