rind

This term describes a protective, often coarse or hardened exterior. It carries a tactile quality of toughness or rigidity, distinguishing it from a thin skin or a soft peel. In culinary contexts, it refers to the boundary between the interior flesh or paste and the external environment. While generally countable when referring to individual pieces of fruit or cheese, the word is often used in an uncountable sense when referring to the material as a food ingredient, such as in pork rind.
