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

What each ingredient does

Butter
Melts into the liquid to give the sauce its rich flavour and smooth body.
Flour
Thickens the boiling water into a smooth, pourable sauce.
Parsley
Adds fresh, green aroma at the end of cooking.

The step that matters

Adding the boiling water while stirring constantly. Flour clumps if liquid is added all at once or without stirring. Constant stirring disperses the starch granules evenly, so the sauce thickens smooth rather than lumpy.

Swap the parsley

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

  1. Capersfits better
  2. Nutmegfits better
  3. Jalapenofits about as well
  4. Parsleythe original

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