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 Caramels
Ingredients
Directions
Make the caramel
Combine grated chocolate, brown sugar, cold water, butter, lemon juice, and vinegar in a saucepan.
Boil over high heat until the mixture reaches a brittle stage. Do not stir; shake the pan gently while boiling.
Set and cut
Once done, pour into a buttered and floured dish.
Cut into squares while still soft.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides the bulk of the sweetness and the caramel flavour as it cooks.
- Grated chocolate
- Adds chocolate flavour and richness to the caramel.
- Butter
- Adds fat, giving the caramel a softer, richer texture.
- Acid vinegar
- Adds acidity that helps prevent sugar from crystallising into a grainy texture.
The step that matters
Do not stir while boiling. Stirring a boiling sugar mixture can encourage crystals to form, which makes the caramel grainy. Gently shaking the pan keeps it smooth while it reaches the target stage.
