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
- Egg yolks
- Thicken the custard and add richness to its texture.
- Flour
- Thickens the custard so it sets smoothly rather than runny.
- Egg whites
- Whipped to stiff peaks, they form a light topping over the custard.
- Sugar
- Sweetens the custard and balances the bitterness of the chocolate.
- Chocolate
- Provides the chocolate flavor and color of the custard.
The step that matters
Boil the mixture until thickened. Stirring constantly over medium heat keeps the flour and egg yolks from scorching or lumping, and the starch must boil to fully thicken the custard.
