Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set with heat and add richness.
- Milk
- Forms the liquid base that the chocolate and yolks thicken into custard.
- Chocolate
- Provides the flavour and colour of the custard.
- Powdered sugar
- Adds sweetness to balance the chocolate.
The step that matters
Adding the egg yolks. Egg yolks thicken through gentle heat, and if the mixture boils too hard or the yolks are added without enough stirring, they can curdle or turn grainy. Keep stirring steadily and stop heating once it thickens.
