Why it works: Chocolate and sugar 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 ↓
Chocolate Custard
Ingredients
Directions
Prepare
Heat the milk in a double boiler.
Grate the chocolate into a bowl.
Make the custard
Add the sugar and egg yolks, then beat until creamy.
When the milk starts to steam, gradually pour it into the chocolate mixture, stirring briskly to prevent lumps.
Return the mixture to the double boiler and cook until thickened like cream.
Chill and serve
Once cooled, pour into a glass dish.
When cold, top with whipped cream before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the custard as they cook and help it set.
- Milk
- Forms the liquid base that the eggs thicken into a custard.
- Sugar
- Adds sweetness that balances the bitter chocolate.
- Sweet chocolate
- Provides the main chocolate flavor and color.
The step that matters
Adding the hot milk to the chocolate mixture. Pouring the hot milk in too quickly can scramble the egg yolks and cause lumps. Adding it gradually while stirring briskly warms the yolks slowly so the mixture blends smoothly.
“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.
