Lobster Soup, or Bisoue

Ingredients

Directions

Prepare the broth and lobster

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

  2. Boil the lobster, extract meat from the body and claws.

  3. Bruise part of the coral and mix with an equal quantity of lobster meat.

Make the meatballs

  1. Add mace, cayenne, salt, and pepper, then form into meatballs using the beaten egg yolk as a binder.

Finish the soup

  1. In 3 quarts of veal broth, add lobster meat cut into pieces and boil for 20 minutes.

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

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

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

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

What each ingredient does

Veal
Breaks down into shreds that give the broth its body and savoury flavour.
Lobster
Provides the main sweet, delicate seafood flavour and tender pieces of meat.
Egg yolk
Binds the seasoned lobster mixture so it holds together as meatballs.
Coral (in the method)
Colours and enriches the soup, and when sieved into the broth it thickens it.
Flour
Thickens the soup when rolled with butter and stirred in.

The step that matters

Simmer gently without boiling. Vigorous boiling can break up the delicate lobster and dull the soup's colour, so the soup should only simmer once thickened.

Swap the mace

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

  1. Parsleyfits better
  2. Nutmegfits better
  3. Capersfits better
  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.
