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

What each ingredient does

Butter
Forms the rich base of the sauce and carries its flavour.
Flour
Thickens the melted butter so the sauce becomes smooth and coats food.
Cold water
Adds moisture and helps the butter and flour form a loose, pourable sauce.

The step that matters

Set the mixture into boiling water and heat until it begins to simmer. Heating too fast or too long can cause the butter to separate or the flour to lump, so the sauce should be heated gently until it just starts to simmer and is stirred smooth.

Swap the capers

The recipe marks capers as optional. How well each one fits the dish's main ingredients (butter, flour, egg, oyster):

  1. Capersthe original
  2. Nutmegfits about as well
  3. Parsleyfits less well
  4. Jalapenofits less well

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