Why it works: Milk and vanilla 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 ↓

Ingredients
Directions
Make the mixture
Grate the chocolate and mix it smoothly with the milk.
Add the sugar and butter, then boil until it hardens when dropped in cold water.
Just before removing from heat, add the vanilla.
Cool and cut
Pour the mixture into shallow pans to cool.
Before it hardens completely, mark it into small squares with a knife.

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, sets the candy's firmness as it cools.
- Butter
- Adds fat for a smooth, rich texture and softens the bite of the caramel.
- Milk
- Adds moisture and creaminess, mellowing the sugar as the mixture cooks.
- Baker's chocolate
- Contributes chocolate flavor and fat, giving the caramel its deep color and body.
- Vanilla extract
- Adds aroma that rounds out the chocolate and dairy flavors.
The step that matters
Boil until it hardens in cold water. Sugar sets firm as its cooking temperature rises. Stopping too early leaves the caramel soft and sticky, while cooking too long makes it hard and brittle.
