What each ingredient does

Egg white
Whipped into a foam that gives the frosting its light, airy structure.
Sugar
Sweetens the frosting and stabilizes the whipped foam as it dissolves.
Corn starch
Helps the frosting hold its shape by thickening and stabilizing the foam.

The step that matters

Beating the egg white until very stiff. Egg white foam must be whipped enough to hold air. Under-beaten whites collapse and make the frosting runny, while the sugar must dissolve fully to keep it smooth and stable.
