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

What each ingredient does

Butter
Provides fat and richness, and carries flavour through the sauce.
Flour
Thickens the butter and water into a smooth, pourable sauce.
Water
Forms the liquid base that the butter and flour thicken.
Hard boiled eggs
Add texture and body when chopped into the sauce for egg sauce.

The step that matters

Mixing the butter and flour into the boiling water. Stirring constantly while the mixture boils keeps the flour dispersed and starch swelling evenly, which prevents lumps and gives a smooth, thickened sauce.

Swap the parsley

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

  1. Capersfits better
  2. Jalapenofits better
  3. Nutmegfits better
  4. Parsleythe original

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