The lemon is a small evergreen tree native to Asia. The tree’s ellipsoidal yellow fruit is used for culinary and non-culinary purposes throughout the world, primarily for its juice, though the pulp and rind are also used in cooking and baking (Wikipedia, nd).

Allergy Alert:

Although it’s rare, you might experience itching, swelling, redness, blisters, bumpiness and dryness of the skin after touching a lemon. More commonly, itching of the mouth, tightness of the throat, coughing or a metallic taste in the mouth can develop after ingesting lemon (Erickson, 2014).

Common Uses:

Lemon juice, rind, and zest are used in a wide variety of food and drink. Lemon juice is used to make lemonadesoft drinks, and cocktails. It is used in marinades for fish, where its acid neutralizes amines in fish by converting them into non-volatile ammonium salts, and meat, where the acid partially hydrolyzes tough collagen fibers, tenderizing the meat, but the low pH denatures the proteins, causing them to dry out when cooked (Wikipedia, nd).
