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

What each ingredient does

Salt cod or ling
Forms the flaked main body of the dish, providing its savoury, meaty base.
Parsneps
Mashed into the sauce, adding body, starch and a mild sweetness.
Cream
Adds richness and a smooth, silky texture to the sauce.
Butter
Contributes fat for richness and a glossy mouthfeel in the sauce.
Flour
Thickens the sauce so it coats the fish rather than running off.

The step that matters

Heat the sauce without boiling. Once the cream and flour mixture reaches a boil it can curdle or separate and become grainy. Gentle heating keeps the sauce smooth and thick.

Swap the white pepper

How well each one fits the dish's main ingredients (vinegar, cream, butter, flour, mustard, pepper):

  1. Tarragonfits better
  2. Capersfits better
  3. Turmericfits better
  4. White pepperthe original

Fit is the average pairing score against vinegar, cream, butter, flour, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
