What each ingredient does

Gelatine
Provides the gel structure that lets the dessert set firm once chilled.
Chocolate
Supplies the chocolate flavour and some body to the set dessert.
Sugar
Adds sweetness and balances the bitterness of the chocolate.

The step that matters

Softening the gelatin before adding the hot mixture. Gelatin must hydrate in cold water first so it dissolves evenly; adding it dry or to very hot liquid without softening can leave lumps and weak setting.
