Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Gelatine
Sets the milk mixture into a firm, wobbly gel once chilled.
Milk
Provides the liquid that hydrates the gelatine and forms the body of the dessert.
Grated chocolate
Supplies the chocolate flavour and dark colour of the set dessert.
Sugar
Adds sweetness and balances the bitterness of the chocolate.

The step that matters

Boiling the chocolate mixture while stirring. Gelatine needs to be fully dissolved and the chocolate evenly blended before setting. Constant stirring prevents scorching on the base of the pan and stops lumps forming, so the final gel sets smooth and even.
