Leeks are a versatile member of the onion family with a rich mild flavor. They combine in the classic leek and potato soup presented in an earlier column and can be sautéed, grilled or added to other soups.
Although they are available throughout the year, they are at their best in New England in the fall. Most farm stands and farmers' markets have them now. Choose leeks with firm, very white bases. Remove the tough outer leaves, but the tender lighter green leaves are very flavorful.
I use a chef's knife and shave away the tough leaves toward the top of the leek, resulting in a tapered top . Because sand accumulates between the layers, slit the leeks lengthwise into four sections, starting above the root end so that they will stay together. Then under running water separate the layers until all the grit is gone. With a little practice this takes only a few minutes.
Vegetable terrines require several steps, but none is difficult. We make asparagus terrines in the spring and use leeks in the fall. Both exude a liquid which congeals enough to hold them together without the need for adding gelatin. The preparation is the same.
Prepare the leeks as above and place into a large pot of boiling salted water (you will need 4 -5 pounds of leeks). When they are quite tender, drain and cool. Select a narrow (3 -4 inches) loaf pan and line it with plastic wrap, leaving extra to cover the top.
Layer the leeks in the bottom, alternating directions to keep the layers level. Cover the top with the plastic wrap. The pan will require draining overnight, and I find a brick or a piece of 2 X 4 cut to the pan length work well. Simply wrap the brick or wood in aluminum foil, place atop the leeks and invert the mold into a shallow pan to catch the juices. The weight of the pan and the leeks compresses the terrine, and the juices run out freely because the terrine is elevated on the wood or brick.
When ready to serve, unmold, leaving the plastic wrap on. Slice crosswise through the plastic using a very sharp or serrated knife. Have a wide spatula next to the terrine so that you can lay the slice onto the spatula. Place on a plate, remove plastic, season with salt and pepper and drizzle with a light vinaigrette. This is a great make-ahead starter for dinner and is sure to impress your guests.
