Lobster Stock Recipes

Steps:

• Remove head sacs (behind eyes) in carapaces; discard. Remove any green tomalley or red roe; reserve for another use or discard. Wrap shells in a clean kitchen towel. Using a rolling pin, meat pounder, or hammer, break shells (some large pieces might remain).
• Heat oil in a Dutch oven or stockpot over medium heat until hot but not smoking. Add shells; cook until fragrant (do not let blacken), about 3 minutes.
• Stir in onions, carrots, celery, and garlic, and fennel (if desired). Cook, without stirring, until vegetables begin to brown, about 3 minutes. Add tomatoes, wine (if desired), peppercorns, thyme, parsley, and bay leaf.
• Fill pot two-thirds with cold water (about 4 1/2 quarts). Bring to a boil. Reduce heat; simmer. Skim froth from surface with a ladle. Cook until broth is aromatic and flavorful, about 1 hour 45 minutes.
• Carefully pour stock through a fine sieve set over a large bowl or container. Discard solids; let stock cool completely. If not using immediately, refrigerate in airtight containers up to 3 days, or freeze up to 2 months.

Steps:

• Bring a large stockpot of water to a rolling boil, add lobsters, and cook at a fast boil until done, about 10 minutes. Transfer to a bowl of iced water to cool, then remove and reserve tail and claw meat for another use. Do this messy job over a bowl to reserve drippings. Crush shells, which will be the base for the stock, using a mallet or hammer, then grind as fine as possible with reserved drippings in a food processor.
• Melt butter and oil in a large stockpot over medium-high heat. Cook onions, carrots, celery, and salt until golden, about 10 minutes. Stir in crushed shells, white wine, and Madeira. Turn heat to high and cook until liquid is reduced by half.
• Add clam juice and tomato juice. Bring to a boil and carefully skim and discard foam that rises to surface. Add remaining ingredients and cook at a simmer, uncovered, 1 hour 15 minutes.
• Strain through a fine sieve and refrigerate up to 2 days or freeze indefinitely.

Steps:

• In a large stockpot, heat the oil over medium-high heat. Add the lobster shells and sauté for 1 minute. Add enough water so that the pot is 2/3 full, then add the onion, bay leaves and peppercorns. Bring to a boil, then reduce heat to low and simmer for several hours or overnight. (The longer it simmers, the better.) Using tongs, remove and discard the large shells, then strain the stock through a fine sieve twice.

Steps:

• With back of a heavy knife crush lobster shells and heads. Chop carrot and onion. In an 8-quart heavy kettle heat oil over moderate heat until hot but not smoking and brown lobster shells and heads, mashing with a wooden spoon to help break up, about 15 minutes. Stir in carrot, onion, tomato paste, and wine and simmer until most of wine is evaporated. Add water and simmer until liquid is reduced to about 4 cups, about 1• hours. Pour stock through a fine sieve into a heat proof bowl. Stock may be made 3 days ahead and cooled, uncovered, before being chilled, covered. Stock keeps, frozen, 3 months.

Steps:

• To make lobster stock:
• Split the lobster carcasses down the middle and remove the grain sac.
• Cook the carrot, celery rib, garlic cloves, bay leaf, and thyme sprig in the olive oil in a 6- to 8-quart pot over moderate heat until softened.
• Stir in the lobster carcasses and water. Bring to a boil and simmer until reduced to about 6 cups, about 11/2 hours.
• Strain through a cheesecloth-lined fine sieve. Cool and refrigerate up to 4 days or freeze up to 3 months.
