Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that gives the sauce its body and smooth, creamy mouthfeel.
- Grated chocolate
- Provides the main chocolate flavor and helps thicken the sauce as it melts into the liquid.
- Egg yolks
- Thicken the sauce as their proteins set with gentle heat, and add richness.
- Sugar
- Adds sweetness and balances the bitterness of the chocolate.
- Rich cream
- Adds fat for a silkier texture and a richer, rounder mouthfeel.
The step that matters
Thickening the mixture over heat. Once the custard base is back on the heat, keep stirring and avoid boiling. Egg yolks thicken by setting as they warm, and too much heat makes them scramble or curdle, leaving a grainy sauce.
