What each ingredient does
- Sugar
- Dissolves into the syrup that gives the frosting its sweetness and body.
- Egg whites
- Whipped into the hot syrup to add lightness and a stable, airy texture.
The step that matters
Boil the mixture to a syrupy consistency. Cooking the sugar and water to the right concentration sets how thick and stable the frosting becomes. Too little boiling leaves it runny, and overcooking makes it stiff and grainy as it cools.
