SYSTEMS AND METHODS FOR DETERMINING DONENESS OF MICROWAVE-HEATED BODIES For determining doneness of a body of food or other material heated in a microwave oven, a device including an indicator that changes appearance at a predetermined temperature, mounted on an outwardlyfacing major surface of a thin-gauge metal element which is disposed in the oven so as to receive heat from the body. The metal element may be mounted on the lid or other wall of a container holding the body in the oven; the lid may be microwave-transmissive and may hold the metal element spaced above the body. The indicator may include a substance that melts at the predetermined temperature to reveal an underlying color or pattern on the metal element surface. In use, the device is placed in a microwave oven together with the body and is observed visually, for detection of the change of appearance, which occurs when the indicator reaches a temperature corresponding to adequate doneness of the body. |
