Ingredients
Greens of 1 leek, well washed
1 sprig parsley
1 fennel frond
3 bay leaves
1 sprig thyme
3 carrots, diced
1 clove garlic
1/2 yellow onion, roughly chopped
1 shallot, roughly chopped
1 cup white wine, preferably Chablis
Preparation
Make a bouquet garni: Cut a piece of kitchen twine about 8 inches long, and tie together leek greens, parsley, fennel, bay leaves, and thyme in a small bundle.
In a large saucepan, combine bouquet garni, 9 cups water, and remaining ingredients. Bring to a boil over medium-high heat. Reduce heat to low, and simmer for 35 minutes. Store in an airtight container, refrigerated for up to 3 days and frozen for up to 3 months.
Just before using, strain through a fine-mesh sieve.
