The leek, is a member of the onion family, but the flavour is much more refined, subtle, and sweet than the standard onion. Thought to be native to the Mediterranean area and Asia, leeks have been cultivated for more than 3,000 years and have long been popular in Europe.
 

With a more delicate and sweeter flavour than onions, leeks add a subtle touch to recipes without overpowering the other flavours that are present.
