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

What each ingredient does

Flour
Thickens the sauce as it cooks, giving it body.
Butter
Adds fat and richness, carrying flavor through the sauce.
Vinegar
Adds acidity that brightens the flavor of the crab.

The step that matters

Simmer without boiling. Simmering gently lets the flour cook fully and thicken smoothly. Boiling can cause the flour to clump and the sauce to separate or turn grainy.

Swap the mace

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

  1. Tarragonfits better
  2. Parsleyfits better
  3. Capersfits better
  4. Macethe original

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