Leeks: the subtle onion
The trees are bare and snowflakes are blowing in the wind. Winter is on the way. One of the few things left to be harvested before the ground freezes are leeks.
These alliums add their distinctive, delicate flavor to all types of culinary delights — soups, stir-fries, salads, and egg dishes. If you haven’t yet tried cooking them, it’s time to enjoy their sweet and subtle touch.
Leeks require a long growing season and mature in our north country in late fall. In warmer climates, they’re harvested in the winter. This makes they’re most abundant from late fall to early spring, making them a great winter vegetable.
If you’re unfamiliar with them, they look like large scallions; like onions, they have many layers and a white bulb that flows into green, tightly wrapped, flat leaves. They should be about an inch in diameter and about a foot long, with bright white bulbs and straight, thick, crisp dark green leaves. Avoid leeks that are wilted, yellow, brown, or slimy. Bigger bulbs can be tough and fibrous.
A relative newcomer to America, leeks have a long history in Europe and Asia. They’re native to a large region stretching from the Mediterranean to India, where they’ve been cultivated for over 3,000 years. During their exodus from Egypt, the Jews complained of the lack of leeks and garlic to season their dishes. Because leeks symbolize the desire for cutting off one’s enemies, they’re traditionally served at Rosh Hashanah, the Jewish New Year festival.
Greek and Roman historians mention leeks, which were thought to be good for the throat and voice. The Romans introduced leeks to northern Europe, where they grew well since they tolerate cool weather. They eventually became the national emblem of Wales, where leek broth or cawl is traditionally eaten on St. David’s Day, March 1 to commemorate King Cadwallader’s victory over the Saxons in 640 AD. The traditional soup, made with meat and root vegetables, is a great warm-up on wintry days.
Allium Porrum (leek) belongs to the allium family, which also includes garlic, onions, shallots and scallions. Many compounds found in allium vegetables are known to protect against colorectal and prostate cancers. While garlic and onions contain higher concentrations of these compounds, leeks are also a good source, and their milder, sweeter taste means that you can eat more of them. In addition, allium vegetables are good for the heart, lowering blood pressure and reducing LDL and total cholesterol while raising HDL, the “good cholesterol” levels.
Leeks are also an excellent source of the minerals manganese and iron, fiber, and vitamin C as well as a good source of vitamin B6 and folate. Taken together, these nutrients help to stabilize blood sugar levels. One cup of raw chopped leeks contains just 57 calories, so they’re great for dieters.
When you bring them home from the market, wrap loosely and store unwashed, untrimmed leeks in the crisper drawer of your refrigerator. You don’t want them to dry out, but wrapping them too tightly in plastic will promote rot.
To prepare them for cooking, cut off the root and the tough green leaves. Use the bulb and stem that are white or light green. Cut them in half lengthwise and rinse under running water to remove sand that is often caught between the layers. Now slice across, then place in a colander and rinse again.
The most famous leek dish is Vichyssoise, a cold pureed leek and potato soup first served in New York City’s Ritz Carlton Hotel by French chef Louis Diat. In addition to soup, their subtle, sweet flavor has graced many traditional and innovative dishes. They’re great added to an omelet or frittata; they’ll add flavor to broths, stews, and soups; and finely chopped raw leeks are great in salads. Leeks make a great alternative to green leaf salad in winter when most of our lettuce comes from South America and California.
