Leek

What is a leek?

Like garlic and onion, leeks are a member of the allium family, but have their own distinct flavour – quite harsh when raw (only very young leeks are eaten this way) but, when cooked, very delicate, like a mild onion with a hint of sweetness. Two thirds of their length is white and firm, and this is the part that is mainly eaten. The rest is made up of the leaves (flags), most of which are discarded.

Leeks are very versatile and work well cooked in various recipes or as a side dish. Two of the world's most famous soups, Scotland's cock-a-leekie and France's crème vichyssoise, are based around them.

How to prepare a leek

Thorough washing is very important for leeks, as soil is often trapped between the many layers of leaves. First, trim off the base, and cut away the uppermost part of the leaves. Remove the outer layer or white, if it's tough. Then, if you want to keep the leek whole, use a knife to make a slit from the top to the point where the green meets the white, cutting through the centre. Rinse well under running water, pulling back the layers so that any dirt at the base is removed. Alternatively, slice the leeks, then put in a colander and wash well under running water.
