Abstract
A device and a method arc disclosed for indicating the reaching of a temperature within a predetermined temperature range by heated food. The device includes a transparent sealed container including a first compartment containing a first substance and a second compartment containing a second substance. The first compartment is separated from the second compartment by a meltable sealant having a melting point within the predetermined temperature range. The device is partially or fully immersed in the heated food and on reaching a temperature within the predetermined temperature range, the meltable sealant melts enabling the first substance to contact the second substance. The contact between the first substance and the second substance results in a detectable change such as a color change of at least one of the first substance and the second substance. The color change is visibly detectable through the transparent sealed container. The device can be made in a variety of shapes and may include an elongated member attached to the sealed container for facilitating the placing of the device within the food.
