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

What each ingredient does

Milk
Provides the liquid base and creamy body of the drink.
Egg yolk
Adds richness and helps thicken the chocolate mixture as it heats.
Baker's chocolate
Supplies the chocolate flavour and the body of the drink.
Egg white
Whipped into stiff peaks to form a light, airy topping.

The step that matters

Boil the mixture until the chocolate separates. Egg yolk thickens when heated but can curdle if the mixture gets too hot or boils too hard, so watch the heat closely while the chocolate melts in.
