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 ↓
Caramel Candy
Ingredients
Directions
Make the candy
In a saucepan, combine sugar and molasses and bring to a boil.
Add milk and continue boiling until the mixture can form a rope, about 25 minutes.
Remove from heat and stir in butter and vanilla.
Cool and cut
Pour the mixture into a buttered pan and let it cool.
Once cooled, cut into squares and allow to harden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides sweetness and, as it concentrates in boiling, the firm set of the candy.
- Molasses
- Adds deep flavour, dark colour and moisture, and contributes to the chewy texture.
- Milk
- Adds creaminess and milk solids that soften the texture and mellow the sweetness.
- Butter
- Adds richness and fat, giving a smoother, more tender bite.
The step that matters
Boiling until the mixture forms a rope. Firmness depends on how far the sugar mixture has concentrated. Stopping early leaves the candy soft and sticky, while cooking too long makes it hard and can scorch the sugars and molasses, giving a bitter taste.
