Why it works: Sugar and chocolate are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
