Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓

Ingredients
Directions
Make the caramel
In a saucepan, combine sugar, glucose, chocolate, salt, butter, and vanilla.
Boil the mixture without stirring until it becomes brittle when dropped into cold water.
Set and cut
Pour the mixture onto buttered tins.
Once cool, cut into squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides sweetness and, as it cooks, the body and set of the caramel.
- Glucose
- Inhibits crystallisation, keeping the caramel smooth and chewy rather than grainy.
- Chocolate
- Adds cocoa flavour and richness to the caramel.
- Butter
- Adds fat for a softer bite and rich flavour.
The step that matters
Boiling without stirring. Stirring can trigger sugar crystals to form, leading to a grainy texture. Boiling to the brittle stage in cold water confirms the sugar has reached the right concentration for a firm set.
