Court-boullion is a traditional poaching broth for fish. Use this to make our Boiled Lobster Tails.
Fill a large stockpot with 7 quarts of water. Make a bouquet garni: Place the herbs, spices, and bay leaves on a square of cheesecloth; tie into a bundle with kitchen twine. Add to pot. Stir in wine, leek, carrots, lemon, and salt.
Cover, and bring mixture to a simmer over medium-low heat. Uncover; gently simmer 30 minutes. Pour through a fine sieve into a large bowl; discard solids. Let cool completely.
If using a fish poacher, fit a 10-quart poacher with the rack in the bottom, and place poacher over two burners. Court-bouillon can be refrigerated in an airtight container up to 1 week or frozen up to 3 months.
