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

What each ingredient does

Pike fillets
Form the main body of the dish, becoming tender and flaky when gently simmered.
Eel fillet
Adds richness and a firmer texture to the fish pieces.
Egg whites
Trap particles as they set, clarifying the broth into a clear liquid.
French rolls
Soak up broth at the base of the tureen, giving a softer, absorbent texture.
Butter
Adds richness and keeps the fillets from sticking to the pan.
White wine
Adds acidity and aroma to the broth as it simmers with the fish trimmings.

The step that matters

Clarifying the broth with egg whites. Egg whites coagulate as they heat, trapping cloudy particles so they can be strained out. If the broth is stirred or boils hard while the whites set, the particles disperse and the broth stays cloudy.

Swap the white pepper

How well each one fits the dish's main ingredients (pepper, fish, mace, onion, parsley, white wine, egg):

  1. Thymefits better
  2. Marjoramfits better
  3. Tarragonfits better
  4. White pepperthe original

Fit is the average pairing score against pepper, fish, mace, onion, parsley, white wine, egg. Candidates are from the same food group and used in at least 100 recipes.
