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 and add the cream.
Bring the mixture slowly to a boil.
Dissolve the chocolate in a small amount of hot water and stir it into the syrup.
Boil gently until a drop in cold water hardens and snaps easily.
Set and finish
Pour onto an oiled slab or into an oiled tin.
When cold, cut into squares with a caramel cutter or a buttered knife.
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 sweetness and, when boiled, forms the firm body of the caramel.
- Cream
- Adds fat and richness, giving the caramel a softer, smoother texture.
- Milk
- Adds moisture and milk solids that contribute to the caramel's flavour and colour.
- Chocolate
- Supplies cocoa flavour and fat, and colours the caramel.
The step that matters
Boil gently until a drop in cold water hardens and snaps easily.. Caramel sets by cooking off water and concentrating sugar. Stopping too early leaves it soft and sticky; cooking too long makes it hard and brittle. Testing a drop in cold water shows when the sugar reaches the right concentration.
