How does a meat thermometer work for cooking?
The level of doneness is correlated to its inner temperature as the meat cooks, so the reading of the temperature indicates when the cut of meat is cooked as desired. It consists of a sharp metal probe, that you can insert into the centre of the food, and a digital display or dial to display the temperature of the meat.
