What each ingredient does
- Sugar
- Sweetens, and as a boiled syrup it stiffens while cooling to give the frosting body.
- Egg whites
- Beaten whites trap air, creating a light, airy foam that gives the frosting volume.
The step that matters
Boiling the sugar syrup. The sugar syrup must reach the stage the recipe describes, because its sugar concentration controls how firm the frosting becomes. Under-boiled syrup leaves a soft, runny result.
