It may resemble an onion -- and make your eyes tear like one -- but the shallot is a vegetable all its own. This bulbous member of the onion family is sweeter and more subtle in flavor than its pungent cousin and resembles garlic with multiple cloves when the outer skin is removed. Varying in color from copper to gray, there are two main types of shallots: Jersey or “false” shallots, which are larger and have a strong flavor, and “true” shallots, which are smaller and milder tasting. Thought to have originated in China around 2000 B.C., shallots have long been a staple in Mediterranean, French, American, and Flemish cuisine. They are often used in salad dressings, stir-fries, and sauces to add flavor and are low in calories and fat-free. They also contain flavonoids, a type of antioxidant found in fruits and vegetables that helps protect the body and may reduce the risk of developing cancer, heart disease, and diabetes. (Garlic, leeks, and onions also have great cancer-fighting nutrients, by the way.) Plus, one tablespoon of chopped shallots is high in potassium, vitamin A, and folate.
