Lobster Soup, or Bisque

Ingredients

Directions

Prepare the broth and lobster

  1. Boil the veal in enough water to cover it until the meat is reduced to shreds, then strain the broth.

  2. Boil the lobster, extract the meat from the body and claws, and bruise part of the coral in a mortar.

Make the force-meat balls

  1. Mix the bruised coral with an equal quantity of lobster meat, adding mace, cayenne, salt, and pepper.

  2. Form the mixture into force-meat balls, binding with the beaten egg yolk.

Make the soup and serve

  1. In a pot, combine 3 quarts of the veal broth with the lobster meat cut into bite-sized pieces and boil for 20 minutes.

  2. Thicken the soup with the remaining coral rubbed through a sieve, then add the force-meat balls and a little butter rolled in flour.

  3. Simmer gently for 10 minutes without boiling to preserve the color.

  4. Serve with small dice of bread fried brown in butter.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much aroma chemistry they share, and how many recipes mention both.

  1. Butter + breadtop 7% of all pairs

    Shared aroma: myristicin (spice, warm).

Butter and flour share little aroma chemistry, yet 124,287 recipes mention both: they likely work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolk
Binds the force-meat balls so they hold their shape when cooked.
Butter rolled in flour
Thickens the soup, giving it a smoother, richer body.
Lobster coral
Colors and flavors the bisque, and thickens it when rubbed through a sieve.
Veal
Provides the meat broth that forms the body of the soup.

The step that matters

Simmer gently without boiling. Once the soup is thickened, a hard boil can break the emulsion of butter and coral, dulling the color and making the texture grainy. Gentle heat keeps it smooth and bright.

Flavor stand-ins for the mace

How well each one fits the dish's main ingredients (veal, lobster, pepper, egg, butter, flour, bread):

  2. Nutmegbetter flavor fit
  3. Capersbetter flavor fit
  4. Macethe original

Fit is the average pairing score against veal, lobster, pepper, egg, butter, flour, bread. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
