What each ingredient does

Granulated sugar
Dissolves into the water and cooks into a syrup that sweetens and sets the frosting.
Egg white
Whipped into a foam that gives the frosting its light, airy structure.

The step that matters

Pouring the hot syrup into the beaten egg white. The syrup must be poured slowly while beating constantly. Pouring too fast or stopping can deflate the foam, and the hot syrup gently cooks the egg white, so the frosting stays smooth and stable.
