Why it works: Vanilla and milk are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Caramels, Chocolate
Ingredients
Directions
Make the caramel
Dissolve the sugar in the milk over low heat.
Add the cream and bring the mixture slowly to a boil.
Dissolve the chocolate in a small amount of hot water, then stir it into the syrup.
Boil gently until a drop of the mixture hardens and snaps in cold water.
Set and cut
Pour the mixture onto an oiled slab or into an oiled tin.
Once cooled, cut into squares with a buttered knife and wrap each piece in wax paper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides the sweetness and, as it cooks down, the firm body of the caramel.
- Cream
- Adds fat for a soft, rich texture that stays tender after cooling.
- Milk
- Adds milk solids and liquid that cook into a creamy, mellow caramel.
- Chocolate
- Supplies cocoa flavour and fat that give the caramel its chocolate character.
The step that matters
Boil gently until a drop of the mixture hardens and snaps in cold water. Sugar syrup sets according to its final temperature, which rises as water boils off. Stopping too early gives a soft, sticky caramel, while cooking too long makes it hard and brittle. Testing a drop in cold water shows when the mixture has reached the right concentration.
