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

What each ingredient does

Lobsters
Provide the main flavour and the tender meat that is warmed through at the end.
Butter and flour
Together they thicken the stock into a smooth, lightly rich body.
Egg
Binds the coral, parsley and bread-crumbs so the forcemeat balls hold their shape.
Bread-crumbs
Add bulk and soft texture to the forcemeat balls.
Cream
Can thicken and enrich the stock, adding body and a softer mouthfeel.

The step that matters

Boil the stock gently for several hours. A gentle simmer extracts flavour from the fish and shells without clouding the liquid or toughening the proteins. A hard boil emulsifies fat and breaks up the stock, leaving it cloudy and less clean-tasting.

Swap the parsley

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

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

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