Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Chocolate
Provides the main flavour and body of the drink.
Egg yolks
Thicken the drink and add richness as they gently set with heat.
Sugar
Adds sweetness that balances the bitterness of the chocolate.

The step that matters

Do not let it boil. Once the beaten egg yolks are added, boiling can curdle them and leave the drink grainy. Heating gently while beating keeps it smooth and evenly thickened.
