The outer skin or rind of a fruit and vegetable. Vegetables that have this outer skin will generally have the peel removed and discarded before the vegetable is used but there are occasions when it is left on. The peel on a fruit is also removed many times but depending on its use, it may be required to remain on the flesh of the fruit. The peel of the fruit also contains essential aromatic oils, which provide flavor to some sweet and savory dishes.
