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 ↓
Chocolate Caramels
Ingredients
Directions
Make the caramel
In a porcelain kettle, combine the chocolate, sugar, molasses, sweet milk, and butter.
Place the kettle on the stove and bring to a boil.
Spoon a little mixture onto a plate to cool.
If the mixture stiffens, stir in the vanilla.
Set and cut
Pour the mixture into greased flat pans.
Once the caramels start to cool, use a knife to mark them into squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Adds deep flavor and color, and firmness as it sets.
- Sugar
- Provides sweetness and, as it cooks, the body that sets the caramel.
- Molasses
- Adds depth of flavor and a chewy, darker character.
- Sweet milk
- Supplies liquid and milk solids that give the caramel a soft, creamy texture.
- Butter
- Adds fat for smoothness and a rich mouthfeel.
The step that matters
Testing the mixture on a plate before adding vanilla. Sugar mixtures set firmly as they cool, so a small cooled sample shows whether the batch has reached the right firmness. Vanilla is added only once the mixture stiffens, because its aroma is delicate and can cook off during prolonged boiling.
