Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks and whites thicken the custard and give it a rich, set texture as they cook.
- Chocolate
- Provides the main chocolate flavor and deep color to the custard.
- Cream
- Adds fat for a smooth, rich mouthfeel and softens the set.
- Fine white sugar
- Adds sweetness and helps balance the bitterness of the chocolate.
The step that matters
Pour the hot mixture over the egg mixture, stirring constantly.. Egg proteins set with heat, so pouring hot liquid into the eggs while stirring constantly tempers them gently. Stopping the stirring can let parts scramble into lumps.
