Ingredients
Directions
Make the syrup
In a saucepan, combine sugar and hot water.
Boil the mixture until it reaches a thick syrup consistency.
Finish the frosting
In a separate bowl, beat the egg white until stiff peaks form.
Slowly stir the syrup into the beaten egg white while continuing to beat until the mixture is cool.

What each ingredient does
- Sugar
- Dissolves into the water to form a syrup that sweetens and sets the frosting as it cools.
- Egg white
- Whipped to stiff peaks, it traps air and gives the frosting its light, fluffy structure.
The step that matters
Slowly stir the syrup into the beaten egg white. Adding hot syrup too fast can scramble or deflate the egg white, while pouring slowly while beating lets the foam absorb heat and stay stable.
