Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Gives the sauce its chocolate flavour as it melts into the hot milk.
- Milk
- Forms the liquid base that carries the melted chocolate.
- Egg yolks
- Thicken the sauce as they cook gently, like a custard.
- Sugar
- Sweetens the sauce and balances the bitterness of the chocolate.
- Cream
- Adds fat for richness and a smoother, silkier mouthfeel.
The step that matters
Cook like a boiled custard. Egg yolks thicken as they heat, but if the mixture gets too hot they scramble and curdle. Cooking gently while stirring keeps the sauce smooth and lightly thickened.
