Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid custard into a firm, sliceable mould as it cools.
- Chocolate
- Provides the main flavour and colour of the custard.
- Egg yolks
- Thicken the custard and add richness through their proteins and fat.
- Milk
- Forms the liquid base that carries the chocolate and thickens with the yolks.
- White sugar
- Adds sweetness to balance the bitter chocolate.
The step that matters
Heat the mixture until hot and smooth. Egg yolks thicken when heated but can curdle if overheated, leaving a grainy texture. Heat gently and keep stirring so the custard stays smooth before the gelatin is added.
