Leeks
Leeks are layered allium vegetables with a tender pale base and firmer green leaves, commonly cleaned, then cooked in soups, stews, braises or roasts.

About Leeks
Leeks are long, layered vegetables in the allium family, with a white to pale-green lower portion and flat, darker-green leaves. The lower portion is tender when cooked, with a mild, sweet onion-like flavour; the leaves are firmer and more pronounced. Dirt can collect between the layers, so the vegetable is commonly split and cleaned before use.
Leeks are used cooked in soups, stews, braises, and other savoury dishes, and can also be grilled or roasted. They are sold whole and fresh, with the usable proportion varying according to how much of the darker leaves is retained. They are not interchangeable in texture with chopped onion, despite a related flavour.
