Lemon peel is the thin, yellow outer covering of the [ingredient=lemon lemon], which is typically used in cooking and baking to provide characteristic lemon aroma and flavor to dishes without the acidity and extra liquid adding [ingredient=lemon-juice lemon juice] would involve. Commercially, lemon peel is mechanically processed to make lemon oil -- there are small glands in the peel that rupture, releasing the oil.

Lemon peel can be cut into small matchsticks or removed from the lemon with a citrus zester to make [ingredient=lemon-zest lemon zest].
