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.
