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 ↓

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, the sugar structure that sets the caramel firm.
- Butter
- Adds fat and richness, giving the caramel a smooth, tender texture.
- Molasses
- Adds deep flavor and moisture, and helps the caramel stay chewy.
- Milk
- Adds moisture and milk solids that contribute to a creamy, chewy texture.
- Chocolate
- Adds flavor and richness, melting into the boiled mixture.
- Sultana raisins
- Add chewy sweetness and bits of fruit texture throughout the candy.
The step that matters
Boil for seven minutes. Boiling drives off water and concentrates the sugar, so the caramel sets firm when cooled. Boiling too briefly leaves it soft, while overcooking makes it hard or grainy.
