Leeks, those long, plump, green cousins to onions and shallots, are a cold-hardy crop.
With their mild, fresh, slightly sweet flavor and grassy aroma, leeks are just right for the shoulder season. They're immensely versatile and a staple in meatless dishes during the Lenten season, adding substance and taste to a range of light, warming dishes.
Leeks are beloved throughout the British Isles. They are to the Welsh what shamrocks are to the Irish and maple leaves are to Canadians. According to legend, early Welsh soldiers were encouraged to wear leeks on their helmets to identify themselves when battling the Saxons.
In our region, they may be overwintered, which explains why we can still find a few local leeks at our farmers markets and co-ops. Look for leeks with the greatest amount of white and light green on their stalks (the most usable portion). The dark green leaves are too tough to eat but are great when simmered in a stock.
To prepare a leek, trim off the whiskers, cut it in half horizontally and retain the pale green part. Then split the leek down the middle vertically. Rinse it thoroughly under cold running water to clean off any dirt.
Leeks are a workhorse in my kitchen. I like to make a leek confit to keep on hand as a base for a variety of pastas, soups, stews and pilafs, to garnish chicken and pork, top off pizza, and for savory tarts. Simply chop several large leeks and cook them gently in butter until very tender and silky. They become more concentrated versions of themselves.
Leek confit will keep for about a week in a covered container in the refrigerator. Or divide the confit into smaller portions and freeze to use when in need of a quick, comforting — and pretty — tart.
