The leek (Allium porrum) is a vegetable belonging to the genus Allium, which also includes onions, garlic, and chives. Leeks are cultivated for their thick, bundled, white and light green leaves, which are used in cooking. The plant has a mild, onion-like flavor and is often used in soups, stews, and salads. Leeks are biennial plants, growing as bulbs in their first year and producing seeds in their second year. They are widely cultivated in temperate climates and have been used in cuisine for thousands of years. In Hebrew, the leek is known as כרשינה (karshina). In French, it is called poireau, and in Spanish, it is referred to as puerro. Leeks are a good source of vitamins A, C, and K, as well as various antioxidants and fiber. They are also notable for their role in traditional dishes such as Welsh rarebit and vichyssoise.
