A timer to indicate to the cook when meat (e.g., turkey) has been roasted to proper temperature includes a closed tube or barrel (11) containing a substance (22) such as wax which melts at that temperature. The tube (11) is inserted into the meat so that it is at the temperature of the interior of the meat rather than the ambient temperature. In the upper end (17) of the tube (11) is an indicator such as a ball and link chain (24) of the type used for key chains. When the wax reaches proper temperature, the chain (24) slides to the bottom of the tube (11). A spring (31) may supplement gravity to urge the chain (24) downward, particularly when the tube (11) is not vertically positioned. |
