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

What each ingredient does

Flour
Thickens the milk into a smooth sauce with the butter.
Egg
Adds richness and helps the mixture set when gently heated.
Milk or cream
Forms the liquid base that the flour thickens into a sauce.
Butter
Adds fat and richness and helps make the flour smooth.

The step that matters

Return to heat without boiling after adding the egg. Boiling after the egg is added can scramble it and cause a grainy texture. Keeping the heat gentle lets the egg thicken the sauce smoothly.

Swap the onion

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

  1. Capsicumfits better
  2. Spinachfits better
  3. Potatofits better
  4. Onionthe original

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