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

What each ingredient does

Butter
Adds richness and a smooth, silky mouthfeel to the sauce.
Flour
Its starch thickens the liquid as it heats, giving the sauce body.
Parsley
Contributes a fresh, herbal aroma and bright green colour.

The step that matters

Heat over medium heat, stirring until it boils. Flour starch only thickens the sauce once it heats up, and constant stirring spreads the butter-flour mixture evenly through the water. Without stirring, lumps can form and the base can scorch on the bottom of the saucepan.

Swap the parsley

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

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

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