What each ingredient does

Butter
Provides fat and richness, and creaming it creates the smooth, spreadable body of the sauce.
Powdered sugar
Sweetens the sauce and dissolves smoothly into the creamed butter, giving it a fine texture.
Egg white
Whipped to stiff peaks and folded in, it lightens the texture and makes the sauce fluffy.

The step that matters

Folding in the stiff egg white. Fold gently so the whipped foam keeps its air. Stirring vigorously deflates the egg white and makes the sauce dense instead of light.
