What each ingredient does

Butter
Provides richness and a smooth, creamy body to the sauce.
Powdered sugar
Sweetens the sauce and dissolves smoothly into the butter for a fine texture.
Egg white
Adds body and lightness as it is beaten into the sauce.
Brandy
Adds aroma and warm, distinctive flavor to the sauce.

The step that matters

Adding the brandy and boiling water. Adding liquid too quickly to the butter and sugar can cause the mixture to separate or look curdled. Adding it gradually while beating keeps the sauce emulsified and smooth.
