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

What each ingredient does

Butter
Adds richness and fat, giving the sauce a smooth, rounded mouthfeel.
Flour
Thickens the sauce as it heats, giving it body and structure.
Egg yolks
Enrich and thicken the sauce, adding body and a smooth, creamy texture.
Cream
Contributes fat and moisture, softening the sauce and making it richer.

The step that matters

Warm the sauce gently until the flour is cooked through. Flour thickens only after its starch granules swell with heat, and it tastes raw if not fully cooked. Egg yolks can curdle if the sauce gets too hot, so gentle heat keeps the sauce smooth while the flour cooks through.

Swap the tomato

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

  1. Leekfits better
  2. Asparagusfits better
  3. Shallotfits better
  4. Tomatothe original

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