Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Light brown sugar
- Dissolves into the boiled syrup that gives the frosting its sweetness and soft body.
- Egg whites
- Whipped to stiff peaks, they add airy volume and help the frosting set light and fluffy.
- Baker's chocolate
- Provides the chocolate flavour and colour throughout the frosting.
The step that matters
Adding the egg whites and chocolate off the heat. Stir quickly once the syrup is off the heat. Sugar syrup that is still very hot can cook the beaten egg whites unevenly, and the frosting thickens as it cools, so it must be spread while still warm.
