What each ingredient does
- Sugar
- Sweetens the frosting and, boiled into syrup, gives it body once beaten into the whites.
- Egg whites
- Whipped to a stiff foam, they create the airy, light structure of the frosting.
The step that matters
Pouring the syrup into the egg whites. The syrup must be hot and poured in a slow, steady stream while beating rapidly. This cooks the whites gently and builds a stable, glossy foam. Pouring too fast or letting the syrup cool can cause the whites to deflate or stay runny.
