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 ↓
Chocolate Caramels
Ingredients
Directions
Make the caramel
Boil the molasses, butter, brown sugar, and flour for 15 minutes.
Stir the grated chocolate into the cream and pour in the boiling mixture.
Continue boiling until done.
Test by dropping a little into cold water; if it hardens, it's done.
Add the vanilla before pouring onto buttered pans.
Set and cut
Pour the mixture onto buttered pans.
As it cools, cut into small squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides sweetness and bulk, and helps the caramel set firm as it cools.
- Molasses
- Adds depth of flavour and a chewy, darker body to the caramel.
- Cream or milk
- Adds moisture and richness, softening the texture of the caramel.
- Butter
- Adds fat for a smooth, tender bite and rich flavour.
- Grated chocolate
- Adds chocolate flavour and colour to the caramel.
- Flour
- Thickens the mixture so it holds its shape when cut.
The step that matters
Testing for doneness in cold water. Caramel sets according to how far its sugar concentration has risen while boiling. A small drop in cold water shows whether it has reached a firm stage. Stopping too early leaves it soft and sticky, while cooking too long makes it hard and brittle.
