Caramel Frosting
Ingredients
Directions
Make the syrup
Boil 1 cup of sugar and ¼ cup of water until it reaches a thread stage.
In another pan, cook ¼ cup of sugar until it reaches the caramel stage.
Add 1-2 tablespoons of boiling water to the caramel and continue cooking until dissolved.
Combine the caramel with the first mixture and cook until it threads again.
Finish the frosting
Pour the hot mixture onto the beaten egg white and beat until cold.

What each ingredient does
- Sugar
- Forms the syrup that sets into a smooth, sweet frosting texture.
- Egg white
- Whipped to foam, it gives the frosting its light, airy body.
The step that matters
Pouring the hot syrup onto the egg white. Pour the hot syrup in a thin, steady stream while beating. Pouring too fast can cook the egg white unevenly or deflate the foam, so the frosting loses its lightness.
