Abstract: A plurality of blocks of resilient material are arrayed in proximity to each other. Each block has a predetermined amount of compressibility which is equal to the amount of compressibility of a model piece of meat which has been cooked to a known degree of doneness. In a preferred embodiment, four blocks will be labeled to indicate the corresponding degrees of doneness of four model pieces of meat which have been cooked to known degrees of doneness, and whose amounts of compressibility are equal to the amounts of compressibility of the blocks being labeled. In the preferred embodiment, the first block will be labeled rare, the second block medium rare, the third block medium well done and the fourth block well done. The degree of doneness of a cooked piece of meat can be measured by compressing the piece of meat and then compressing the blocks to determine which block has an amount of compressibility equal to the amount of compressibility of the cooked piece of meat.
