ABSTRACT:
A cooking appliance, which automatically toasts bread, and has a heater, a gas sensor, and a thermistor. The gas sensor detects moisture which comes from the bread. The thermistor detects the temperature within the cooking cabinet. A microcomputer measures gas driven from bread during toasting to determine whether the bread was initially frozen or not. The time of gas sensor reading is determined based on an initial temperature within the cooking cabinet so that the decision will not be made inaccurately due to repeated use of the cooking appliance.
