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

What each ingredient does

Butter
Adds richness and flavor, and carries the sauce's smooth, silky mouthfeel.
Flour
Thickens the sauce as it cooks into the boiling water, giving it body.
Hard-boiled eggs
Chopped into the sauce to make an egg sauce, adding texture and richness.

The step that matters

Stirring the butter-flour mixture into the boiling water. Adding the roux-like paste to boiling liquid all at once, while stirring, helps prevent lumps. Stirring keeps the starch dispersed so it thickens evenly.

Swap the parsley

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

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

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