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 set, creamy structure.
- Milk
- Forms the liquid base of the custard and adds richness and softness.
- Baker's chocolate
- Provides the chocolate flavor and dark color of the custard.
- Sugar
- Sweetens the custard and the whipped egg white topping.
- Vanilla
- Adds a warm aroma that rounds out the chocolate flavor.
The step that matters
Add the eggs only when the chocolate mixture is nearly cold. Egg proteins begin to set around moderate heat, so beating eggs into a still-hot liquid can scramble them and leave a grainy custard. Cooling the mixture first lets the eggs blend in smoothly and thicken gently.
