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
Combine butter, chocolate, molasses, brown sugar, cream, and vanilla sugar in a granite saucepan.
Stir over low heat until thoroughly mixed.
Boil slowly until the mixture hardens when a little is dropped in ice water.
Set and cut
Pour into greased shallow pans and let cool.
When nearly cold, dip a sharp knife in olive oil and mark into small squares.
Once completely cool, break apart and wrap in wax paper if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat for a soft, rich texture and smooth mouthfeel.
- Brown sugar
- Provides sweetness and moisture, and helps the caramel set chewy.
- Molasses
- Adds deep flavour and moisture, and darkens the caramel.
- Grated unsweetened chocolate
- Supplies chocolate flavour and colour, and adds fat for richness.
- Cream
- Adds fat and moisture, giving a softer, creamier bite.
The step that matters
Boil slowly until the mixture hardens in ice water. Sugar concentration determines firmness once cooled. Boiling too briefly leaves caramels sticky and soft, while overcooking makes them hard and brittle. The ice water test checks that the mixture has reached the right stage.
