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

What each ingredient does

Lobsters
Provide the sweet, tender meat that is warmed in the finished soup.
Egg
Binds the coral and crumbs together so the forcemeat-balls hold their shape.
Bread crumbs
Add body to the forcemeat-balls and absorb moisture from the coral mixture.
Butter
Enriches the stock and, with flour, forms a roux that thickens it.
Flour or cream
Thickens the strained stock, giving it a smoother, more body-rich texture.
Coral of the lobster
Adds rich lobster flavour and colour to the forcemeat-balls.

The step that matters

Thicken the strained stock. Flour or cream must be fully incorporated and the stock kept at a gentle simmer so it thickens smoothly without lumps or scorching. Adding thickener to a boiling liquid or unmixed flour can cause clumping.

Swap the parsley

How well each one fits the dish's main ingredients (beef, lobster, fish, bread, egg, 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, bread, egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
