Leeks are a member of the lily family. They thrive in cooler weather, and even taste better after exposure to several frosts. In France, the inside of fat leeks are boiled and called "poor man's asparagus. Rather than forming a tight bulb like the onion, the leek produces a long cylinder of bundled leaf sheaths that are generally blanched by pushing soil around them (trenching). Make sure to wash the leeks thoroughly before using, as they are known to have quite a bit of soil between the leaf sheaths.
