Leeks are related to onions, scallions, shallots, and garlic but have a sweeter and more delicate taste. Their subtle flavor adds a mild punch to recipes without overshadowing other ingredients. Leeks from Holland are especially delicious due to the growing conditions in their native country. Holland leeks are cleaner, fresher, and have a flavor second to none. One cup of leeks packs only about 50 calories and is a good source of iron and Vitamin C. Characterized by a long, thick stem and bulbous roots, leeks are topped off by broad flat green leaves. A member of the Allium family, leeks are believed to help in the reduction of LDL (bad cholesterol ) while raising HDL (good cholesterol). An essential ingredient in soups or salads, leeks have been popular for thousands of years.
