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

What each ingredient does

Butter
Melts to form the fat base that carries the flavor of the sauce.
Flour
Its starch swells in the hot liquid and thickens the sauce.
Eggs
Chopped cooked eggs add body, richness and flavor to the sauce.

The step that matters

Gradually pour in the hot water, stirring constantly. Flour starch clumps when liquid is added too fast. Pouring slowly while stirring disperses the starch evenly, so the sauce thickens smoothly without lumps.
