Peel (fruit) The peel of citrus fruits is bitter and generally not eaten raw, but may be used in cooking. In gastronomy, the outermost, colored part of the peel is called the zest, which can be scraped off and used for its tangy flavor. A large piece of citrus peel, called a "twist", is often used to garnish cocktails. The fleshy white part of the peel, bitter when raw in most species, is used as succade or is prepared with sugar to make marmalade or fruit soup. The peel can also be candied, or dried to produce a seasoning (e.g. chenpi).
