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

What each ingredient does

Butter
Enriches the sauce and adds richness to the base.
Flour
Thickens the milk into a smooth white sauce as it cooks with the butter.
Milk
Forms the liquid base that thickens into the sauce.
Hard boiled eggs
Provide the main body and protein of the dish, folded through the sauce.

The step that matters

Gradually add the milk, stirring constantly until the mixture thickens. Adding milk slowly while stirring keeps the flour evenly dispersed, preventing lumps. Constant stirring lets starch granules swell and gelatinize smoothly as the sauce heats, producing an even, thickened texture.

Swap the white pepper

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

  1. Nutmegfits better
  2. Capersfits better
  3. Cinnamonfits better
  4. White pepperthe original

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