Directions

Make the stock

  1. Chop a lobster and add it to a pot with 1 quart of beef gravy and the shells of the lobster.

  2. Clean and cut small fish into pieces and add them to the pot.

  3. Boil the mixture gently for several hours.

Make the forcemeat balls

  1. Pound the coral of the lobster in a mortar with a small piece of the stock.

  2. Mix the pounded coral with chopped parsley, bread crumbs, and 1 egg to form forcemeat balls.

Finish and serve

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

What each ingredient does

Lobster
Provides the sweet, delicate meat and flavour that defines the soup.
Beef gravy
Forms the savoury base liquid that the lobster and fish flavour during simmering.
Egg
Binds the parsley and bread crumbs so the forcemeat balls hold their shape.
Bread crumbs
Absorb moisture and add body to the forcemeat balls.
Butter
Adds richness and fat, and helps thicken the stock when combined with flour.
Flour
Thickens the stock to give the soup a smoother, fuller body.

The step that matters

Boiling the stock gently for several hours. A gentle simmer extracts flavour from the shells and fish without clouding the broth. A hard rolling boil can emulsify fats and make the stock cloudy and greasy.

Swap the parsley

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

  1. Capersfits better
  2. Nutmegfits about as well
  3. Tarragonfits about as well
  4. Parsleythe original

Fit is the average pairing score against beef, lobster, fish, egg, bread, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
