What each ingredient does
- Sugar
- Provides sweetness and, when boiled, forms the syrup that sets into the frosting's body.
- Egg whites
- Whipped into the hot syrup to add airy volume and a light, fluffy texture.
The step that matters
Boil sugar and water to a soft ball. Sugar syrup must reach the right concentration to set properly. Under-boiling leaves the frosting runny, while over-boiling makes it hard and grainy as it cools.
