Firstly, lemon peel is the whole skin of the lemon, including the white part, that is everything but the flesh. It is medicinal to some extent because of the vitamins, minerals and fibers which makes it beneficial to one’s health.
Meanwhile, it is rare to use the peel in recipes because of the white portion that tastes bitter and if at all you are going to use it for anything make sure you wash your lemon peel very well because of insecticides and pesticides. Lemon peel can be used as a flavor in teas.
Zest refers only to the thin colored part of the peel which is used for seasoning food. it should not contain the white part, as it is bitter. You can zest a lemon by using a lemon zester or grater. Zest is actually the bright flavor of the fruit be it lemon, lime or orange.
