Organic Leeks are a wonderfully versatile vegetable; they have a long white stalk, dark green leaves and shallow roots. When preparing trim the root end and any tough green leaves. Cut vertically to the centre of the entire length of the stalk, fan open and wash thoroughly under cold water. They make a great addition to stews, casseroles, soups and stir-fries. The baby leek variety is an excellent gourmet option. Leeks are a good source of vitamin C and iron.
