Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the sauce as they set, giving it a soft, custard-like body.
- Flour
- Thickens the melted butter into a roux that helps the milk form a smooth sauce.
- Butter
- Carries the flour and adds richness to the base of the sauce.
- Milk
- Forms the liquid base of the white sauce, adding moisture and body.
The step that matters
Stirring the eggs into the sauce. Eggs set when heated, so they can curdle or turn grainy if the sauce is too hot or left unstirred. Constant stirring over gentle heat keeps the mixture smooth as it thickens.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, flour, milk, egg, spread, anchovy):
- Nutmegfits better
- Capersfits better
- Parsleyfits better
- White pepperthe original
