Getting to Know Leeks

For many of us, leeks are less familiar than the other members of the allium family: garlic, shallots, scallions and onions of all colors.
Leeks look like scallions on steroids. Generally only the white part and the tenderest parts of the green parts are used. Their mild flavor should be a welcome addition to soups and many other dishes.
Here are a few to start you off.
Recipes from French cuisine, the mother of all cuisines. Provencal and other regional favorites. Geared to the home cook.

Cock-a-Leekie Soup

No potatoes, so not traditional, and with apologies for the British measures

Cock-a-leekie soup is a traditional Scottish soup dish of leeks, potatoes, and chicken stock.

½ tsp. sugar
7 cups water or more
1 large carrot, sliced
Black pepper powder
1 chicken broth cube
Salt and pepper to taste

Directions:
1. Combine tumeric powder and chicken, mix well.

2. In a cooking pot, combine water, onion and ginger, bring to a boil. Add chicken and cook for 20 minutes with low heat, then add white part of leeks, cook for 10 minutes more.

3. Take out the chicken from the soup, discard the bones and skin then return to the pot.

4. Add the green part of the leeks, coriander powder, tomato paste, sugar, black pepper powder and broth cube. Simmer for 15 minutes.

Braised Leeks with Blue Cheese

4 leeks, washed well and sliced thinly
3 cloves garlic, peeled and sliced paper thin
2 tablespoons olive oil, more if needed
1/4 cup blue cheese crumbles

1. Heat oil in a skillet over low heat. Add garlic and heat slowly until it begins to flavor oil, about 2 minutes.

2. Add leeks and toss gently to coat with oil and garlic.

3. Add 2Tbsp water, reduce heat, cover, and cook about 10 minutes until leeks are soft.

4. Remove lid, increase heat, and stir until thoroughly cooked, and most of the moisture is removed.

5. Sprinkle blue cheese crumbles over each serving.

Serve hot as a side dish.

Leeks with a Shallot-Caper Vinaigrette

4 small to medium leeks (about 1 pound untrimmed)
1 1/2 teaspoons Sherry vinegar* or white-wine vinegar, or to taste
1 tablespoon minced shallot
1/2 teaspoon Dijon mustard
2 tablespoons extra-virgin olive oil
1 teaspoon drained capers, chopped fine
1 tablespoon minced fresh parsley leaves

1. Trim leeks to about 5 inches and trim root ends, leaving them intact. Cut each leek in half lengthwise and wash well, discarding any tough outer leaves.

2. In a skillet just large enough to hold them in one layer arrange leek halves, cut sides down, and add enough water to reach halfway up sides of leeks. Simmer leeks, covered, until tender, 5 to 10 minutes, and immediately plunge into a bowl of ice and cold water.

3. In a small bowl whisk together vinegar, shallot, mustard, and salt and pepper to taste and add oil in a stream, whisking. Whisk vinaigrette until emulsified and whisk in capers and parsley.

4. Transfer leeks to paper towels. Pat and gently squeeze leeks until dry and divide between 2 plates. Spoon vinaigrette over each serving.

Crustless Smoked Salmon, Leek, and Mushroom Quiche

This crustless quiche is easy to make, and is great for any meal. Plain canned salmon will work in this recipe, too. Onions or shallots can be substituted for the leeks.

Ingredients:
1 large leek, with white and light green parts sliced (about 1 cup of slices)
1 small red pepper, chopped (about half a cup)
4 oz raw mushrooms (wild or shitake are nice for this, but any will do)
1/2 teaspoon thyme
6 - 8 ounces smoked salmon
3/4 cup shredded cheese - almost any kind or a combo
4 eggs
1 and 1/2 cup milk, cream, unsweetened soy milk, or a combination
1 teaspoon dry mustard
pinch of cayenne pepper or a bit of hot sauce, salt, and pepper
paprika for garnish

Preparation:
1. Preheat oven to 375 F.

2. Saute' leeks in a little olive oil. When they begin to soften, add peppers, mushrooms and a little salt. Continue cooking for for 4 - 5 minutes. Just before taking off heat, add the thyme.

3. Crumble salmon in pie plate. Cover with vegetables and then sprinkle with the cheese.

4. Whisk together eggs, milk, mustard, cayenne or hot sauce, salt (about 1/2 teaspoon, but less if salmon is salty), and pepper.

5. Pour the egg mixture over the rest of the ingredients.

6. Bake for 35-50 minutes. Start checking after half an hour. If it's getting too brown but the middle is too liquid, cover with foil. When done, the center will still be a bit loose. Take it out of the oven and let it sit for at least 5 minutes. It will continue to cook and the center will firm up.

Serve sprinkled with paprika.

Leek and Cheese Tart

I suspect a quiche pan or pie pan may substitute for the chef's ring.

For the pastry base:
110g/4oz plain flour
1 egg
110g/4oz butter, cubed
cold water, as needed
extra flour, for dusting

For the filling:
30g/1oz butter
½ leek, diced
1 garlic clove, crushed
2 tsp fresh thyme, chopped
85g/3oz peas
salt and freshly ground black pepper, to taste
110g/4oz dolcelatte cheese*, crumbled
2 eggs, beaten
150ml/5fl oz double cream
green leaves from the leek, shredded and deep-fried, for garnish

Method
1. Preheat the oven to 200C/400F/Gas 6.

2. For the pastry, place the flour, egg and butter into a food processor. Pulse until well combined, adding just a little water, if necessary, to bind.

3. Turn dough out of the processor onto a lightly floured surface, and roll out to a 25cm/10in circle.

4. Place a large chefs' ring onto a baking sheet, and line it with the pastry, pressing down well on all sides.

5. Place into the hot oven for 2-3 minutes. Remove from oven.

6. To make the filling, while the pastry case is cooking, heat the butter in a frying pan over a moderate heat.

7. As the butter begins to melt, add the diced leek, garlic, thyme and peas.

8. Sauté for 3-4 minutes.

9. Season to taste, then pour into the partly-cooked pastry case.

10. Crumble the cheese on top of the leek mixture.

11. Mix the eggs and cream together in a separate bowl, season to taste, then pour over the filling in the pastry case.

12. Place back into the hot oven for 15 minutes, or until set and golden.

13. Remove from the oven, slide onto a serving plate, remove chefs' ring and garnish with the deep-fried leek tops to serve.

Cheesy Leek Quiche

In a crust if you want. In any case an easier recipe than the tart, above.

2 tablespoons butter
2 cups sliced leeks
1 (9 inch) frozen pie crust, thawed
1 cup shredded Swiss cheese
1/4 cup grated Romano cheese
1 tablespoon all-purpose flour
4 eggs
1 3/4 cups heavy cream
1 tomato, thinly sliced
salt and pepper to taste

DIRECTIONS
1. Preheat oven to 450 degrees F (230 degrees C).

2. Melt the butter in a skillet over medium heat, and saute the leeks until tender. Spread evenly over the bottom of the pie crust.

3. In a bowl, toss together the Swiss cheese, Romano cheese, and flour. Spread over the leeks.

4. In a separate bowl, beat together the eggs and heavy cream. Pour over the cheese layer in the pie crust. Top with the tomato slices, and season with salt and pepper.

5. Bake 15 minutes in the preheated oven. Reduce heat to 325 degrees F (165 degrees C), and continue baking 30 minutes, until the crust is lightly browned and a knife inserted in the center of the quiche comes out clean.
