Zest is the fragrant grated outer peel of a lemon or orange. Lemon zest, grate the zest, a strip of zest.
Only the coloured layer is wanted, because the white pith beneath is bitter, and the oil in it carries most of the smell of the fruit. Zest also means keen enjoyment, as in a zest for life, which came from the cookery sense.
