Lobster Bisque (Bisque de Homard)

Ingredients

Method

1. 01
   Prepare the lobster and extract the meat. If starting from whole cooked lobsters: twist off the claws and arms, crack them and extract the claw meat. Pull the tail from the body, cut lengthwise, and remove the tail meat. Reserve all the meat refrigerated. Using a heavy knife or mallet, roughly chop or crush all the shells — head, body, legs, claw shells — into pieces no larger than 4 cm. The more surface area exposed, the more flavor is extracted. Collect any juices that run out and add to the pot.
2. 02
   Roast the shells to build flavor. Melt the butter in a large, heavy pot over the highest heat. Add the crushed shells and sauté, stirring and pressing frequently, for 6 to 8 minutes. The shells will turn a deep, vivid red-orange and the kitchen should smell intensely sweet and oceanic. This step — the Maillard reaction on the shell surface — is the single most important technique in the recipe. Do not rush it: under-roasted shells produce a pale, flat bisque.
3. 03
   Build the base. Reduce the heat to medium. Add the onion, carrots, celery, and shallots to the shells and cook 5 minutes, stirring. Add the garlic and tomato paste and cook, stirring constantly, for 2 minutes until the tomato paste darkens from red to a deep, rusty caramel — this removes its raw flavor and intensifies the color. Remove from heat. Add the cognac and, if desired, tilt the pan to ignite or simply return to heat and cook 2 minutes until the cognac reduces by half. Add the white wine and reduce by half.
4. 04
   Simmer and strain. Add the fish stock, tarragon, bay leaves, and cayenne. Bring to a boil, then reduce to a steady simmer and cook uncovered for 35 to 40 minutes. The stock will reduce and deepen in color. Remove from heat. Using tongs, remove and discard the large shell pieces. Transfer the remaining mixture — including smaller shells, vegetables, and liquid — to a blender and blitz in batches until as smooth as possible. Pass through a fine-mesh sieve or chinois, pressing hard to extract every drop of flavor from the solids. Discard all solids.
5. 05
   Finish with cream, mount with butter, and serve. Return the strained bisque to a clean pot. Bring to a gentle simmer. Stir in the double cream and simmer 5 minutes until the bisque coats the back of a spoon. Taste and adjust salt, pepper, and cayenne. Remove from heat and whisk in the cold butter one piece at a time — this mounts the soup, giving it a glossy sheen and silky body. Warm the reserved lobster meat briefly in a little butter. Ladle the bisque into warmed bowls, add the lobster meat pieces, swirl a tablespoon of cream across the surface, and scatter chives or tarragon. Serve immediately.
