Lemon peel is literally the skin of the lemon. If you cut a lemon, you will see that there are 2 obvious layers of skin on a lemon, an outer yellow layer, and a white inner layer. Lemon rind, on the other hand, is just the yellow layer of the skin. It is also sometimes known as lemon zest. The white part is often known as the pith. Lemon rind is widely used in cooking and baking. It is rich in lemon oil that gives any baked goods or other food it is added to a lovely citrus aroma. It still tastes bitter, which is why is it normally used in small quantities and often finely grated before being added into any food or drinks. Other than the rind that is mostly used in cooking and baking, the skin of the lemon is often discarded. These candied lemon peels are a great way of using up the lemon skin. The peels are cut into thin strips, cooked in sugar syrup until they turn translucent, and then given a coating of granulated sugar to turn them into a yummy snack.
