Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid into a firm, sliceable structure as it cools.
- Chocolate
- Adds chocolate flavour and a rich, dense body to the mixture.
- Egg yolks
- Thicken the custard and add richness and smoothness through their proteins and fat.
- Milk
- Adds creaminess and softness, making the custard smooth and mild.
- Sugar
- Sweetens the dessert and softens its flavour balance.
The step that matters
Cook the custard in the double boiler. Egg yolks thicken as they heat, but overheating scrambles them into lumps. Gentle, steady heat in a double boiler keeps the custard smooth.
