Abstract
A disposable type cooking thermometer having a reservoir for holding a fluid, an indicator means, and a capillary tube or channel connecting the reservoir with the indicator means. The reservoir is made from a material which shrinks from an initial size at ambient temperatures to some smaller size when exposed to cooking temperatures. As the reservoir progressively shrinks during cooking, fluid is expelled therefrom thru the capillary tube or channel and onto the indicator means to denote the degree of cooking achieved in the foodstuff in which the thermometer has been inserted.
