What each ingredient does
- Butter
- Provides fat and richness, and creams with the sugar to give the sauce its body.
- Powdered sugar
- Adds sweetness and bulk, and dissolves smoothly into the butter for a fine texture.
- Boiling water
- Loosens the mixture slightly so it whips into a smoother, lighter cream.
The step that matters
Whip until creamy. Whipping long enough dissolves the powdered sugar fully into the butter. Under-whipped sauce stays grainy, while the fat stays firm enough to hold air.
