What each ingredient does
- Granulated sugar
- Provides sweetness and, once boiled into syrup, sets into a glossy, firm frosting as it cools.
- Egg white
- Its beaten proteins trap air to form a light foam that gives the frosting body and volume.
The step that matters
Pouring the hot syrup into the egg white. Pour the syrup slowly while beating constantly. Adding it too fast can deflate the foam, and stirring keeps the heat spread evenly so the egg white cooks gently, giving a smooth, stable frosting.
