Leek

The leek (Allium porrum) is a vegetable plant in the Amaryllidaceae family, alongside onions, garlic and chives. It is a biennial plant grown as a vegetable: during its first year, it develops a long pseudostem made of overlapping leaves; if left in the ground, it can flower the following year. The tender white part we eat is mainly formed by the bases of the leaves.

It stays pale because it receives little light, especially when soil is drawn up around the plant. The green leaves are also edible, although they are firmer. Leeks grow well in deep, fertile, loose soil that retains moisture. They tolerate cold fairly well and, depending on the climate and variety, can remain in the garden through part of the winter.

In cooking, leek is valued for its mild, slightly sweet flavor, similar to onion but usually less pungent. It can be eaten raw, especially when young, or cooked in soups, savory tarts, gratins, sauces and vegetable dishes. Before cooking, the roots and damaged parts are removed, and the leaves should be rinsed carefully because soil can remain between their layers.

Leeks provide fiber, vitamin K, folate and sulfur-containing compounds characteristic of the Allium genus. Their nutritional composition varies according to the part eaten, the variety and the cooking method. Leek is a common, versatile vegetable that can easily be included in a varied diet.
