Zest (ingredient)

Zest is a food ingredient that is prepared by scraping or cutting from the rind of unwaxed citrus fruits such as lemon, orange, citron, and lime. Zest is used to add flavor to many different types of food. In terms of fruit anatomy, the zest is obtained from the flavedo (exocarp) which is also called zest. The flavedo and white pith (albedo) of a citrus fruit together makes up its peel. The amounts of both flavedo and pith are variable among citrus fruits, and may be adjusted by the manner in which they are prepared. Citrus peel may commonly be used fresh, dried, candied, or pickled in salt.
