Leeks belong to the same family as onions, shallots, scallions, chives, and garlic. They look like a giant green onion but have a much milder, somewhat sweet flavor and a creamier texture when cooked. Leeks are usually cultivated, but wild varieties, such as the North American wild leek — also known as ramps — are gaining popularity. Ramps are popular with foragers and top chefs alike due to their potent flavor, which is a cross between garlic, scallions, and commercially grown leeks. All varieties of leeks are nutritious and thought to offer a host of health benefits.
