Use like onions as a base in recipes, like soups, sauces
and vegetable sautés. You can roast or grill
them, cut in half. Leeks have a slightly different flavor
than onions and are very sweet. Cook them slowly over
medium heat, and use in a tart with goat cheese or as
a relish on steak or stir into cooked beans. They will
make a good side dish on their own.
To wash leeks, cut them first and put them in a bowl
of cool water, swish them around and allow any dirt
and sand to fall to the bottom of the bowl. Then scoop
out the leeks from the top. In a pinch, cut in half
and rinse under water, concentrating on removing the
dirt from the outer leaves.
Leeks will store for several weeks in the refrigerator.
They could be frozen for long term storage, but their
flavor will change slightly. Save the greens in the
freezer for use in stocks, for soup.
