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

What each ingredient does

Butter
Adds richness and fat, giving the sauce a smooth, rounded mouthfeel.
Flour
Thickens the butter and water mixture into a smooth sauce as it cooks.
Hard-boiled eggs
Add body and texture, with their mild richness folded into the sauce.

The step that matters

Stir the mixture into the boiling water. Adding the butter and flour paste to boiling liquid, while stirring, disperses the flour so it thickens smoothly rather than forming lumps.
