What each ingredient does

Egg whites
Whipped into a stiff foam that gives the icing its light, airy structure.
White sugar
Sweetens the icing and stabilises the whipped foam as it dissolves into it.
Grated chocolate
Adds chocolate flavour and colour to the icing.

The step that matters

Beating the egg whites to a stiff froth. Egg whites must be whipped until they hold stiff peaks, since their protein network traps air and gives the icing its volume. Under-whipped whites stay runny and deflate, and grease or yolk residue in the bowl can prevent them from whipping properly.
