Garlic

Garlic (scientific name: Allium sativum) is a small plant closely related to the onion (Allium cepa). It is grown for its underground bulb, which consists of several small segments all contained within a single protective layer. Each small segment is called a clove or bulbil.

Garlic is used worldwide as a flavoring and culinary ingredient. It has a sharp, pungent taste and smell that comes from sulfur-containing compounds. When garlic is cut or crushed, these compounds break down and form allicin, which is responsible for its distinctive odor.

Plant characteristics

Garlic is an annual or biennial plant with long leaves that are flat and green. The underground bulb is the edible part. The individual cloves are typically white or pale brown in color. The plant can produce a long flower stalk, but most growers cut these off to redirect the plant's energy to bulb development.

Cultivation

Garlic is typically not grown from seed, but rather propagated directly from cloves—each planted clove grows into a new plant. It requires soil that drains well and plenty of sunlight. In many regions, planting occurs at the end of the rainy season, with harvesting in summer when the leaves begin to dry. After harvest, the bulbs are dried for long-term storage.

Culinary uses

Garlic is a basic ingredient in the cuisines of the Mediterranean, Asia, the Middle East, and Africa. It is used fresh, cooked, roasted, or dried and ground into powder. Cooking mellows its harsh flavor and imparts a mild sweetness. Black garlic, found in East Asia, is garlic that has been fermented and heated gradually until its color darkens.

Health and culture

Many cultures have traditionally used garlic as a remedy. Modern research has examined its potential effects on blood pressure and cholesterol, though findings remain inconsistent. It is also well known in the stories and customs of various peoples, where it has been used as a protective talisman.
