Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate Caramels
Ingredients
Directions
Make the caramel
Combine water, milk, and molasses in a large saucepan; add sugar and stir until dissolved.
When the mixture boils, add the chocolate and let it melt without stirring.
Add the butter and do not stir after this point.
Test the mixture by wetting a finger, dipping it into the boiling mixture, then plunging it into cold water; it should not burn your finger.
When the candy hardens to the breaking point in water, remove it from heat.
Set and cut
Pour the mixture quickly into a buttered tin, avoiding scraping the saucepan to prevent sugar crystallization.
Let the candy cool, then cut into squares and wrap each square in oiled paper.

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, forms the firm caramel structure.
- Butter
- Adds fat for a soft, rich texture and smooth mouthfeel.
- Glucose
- Interferes with sugar crystal formation, keeping the caramel smooth rather than grainy.
- Dark molasses
- Adds deep flavour and colour, plus extra moisture and softness.
- Milk
- Contributes milk solids that add creaminess and help the caramel brown.
- Unsweetened chocolate
- Adds chocolate flavour and fat, deepening the richness of the caramel.
The step that matters
Avoid scraping the saucepan when pouring. Scraping can dislodge sugar crystals from the pan sides into the batch, where they can seed crystallization and make the caramel grainy.
