What each ingredient does
- Granulated sugar
- Forms the syrup that sets into a sweet, smooth frosting structure.
- Egg white
- Whipped into a foam that the hot syrup stiffens and lightens.
- Cold water
- Dissolves the sugar so it can be boiled into a syrup.
The step that matters
Boiling the syrup to the thread stage. Sugar syrup must reach the right concentration to set properly. Boiling too little leaves the frosting runny, while boiling too far makes it hard and grainy. Watching for the thread or hair stage gives a clear sign of the correct point.
