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

What each ingredient does

Butter
Creams with the sugar to give the sauce a light, smooth, rich body.
Powdered sugar
Sweetens the sauce and dissolves smoothly into the creamed butter.
Egg whites
Whipped to stiff peaks, they add airiness and a light, fluffy texture.
Egg yolk
Adds richness and helps emulsify the butter and sugar into a smooth mixture.

The step that matters

Folding in the egg whites. Whipped whites hold air, and overmixing or stirring them vigorously after folding in deflates the foam, making the sauce dense rather than light.
