- 1 1/2 teaspoons extra-virgin olive oil
- 3-4 lobster heads (tail and claws removed), cut in 3 or 4 pieces (see Helpful Hint)
- 3 tablespoons Cognac
- 2 plum tomatoes, sliced
- 1 tablespoon tomato paste
- 2 large or 4 small leeks, cut in half lengthwise and washed well
- 1 medium-size onion, sliced
- 2 celery stalks, cut in half
- 1 head of garlic, cut across the middle to expose the cloves
- 6 sprigs of fresh flat-leaf parsley
- 2 bay leaves
- 12 whole black peppercorns
- 6 sprigs of fresh thyme
- 3 sprigs of fresh tarragon
Heat an 8-quart stockpot over high heat for about 2 minutes. Add the olive oil and lobster and saute until the shells turn bright red.
Remove the pan from the heat, add the Cognac, then return to the heat and allow the alcohol to burn off, about 15 to 20 seconds. Add the tomatoes and tomato paste and stir. Add the remaining ingredients and cover with cold water.
Bring to a boil over high heat, skim, and reduce the heat. Simmer gently for 1 to 1 1/2 hours. Cool slightly and strain through a fine sieve. The stock will keep for 2 to 3 days in the refrigerator, or freeze in 1-cup batches.
