Why it works: Sugar and molasses are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. 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, sets into a hard, brittle candy structure.
- Butter
- Adds fat for richness and a smoother, more tender bite in the finished candy.
- Molasses
- Adds deep flavor, color, and moisture, and contributes to the candy's sweetness.
The step that matters
Boil until brittle in cold water. Sugar syrup hardens as its water boils off. Stopping too early leaves a sticky, soft candy, while boiling too long can scorch the molasses and sugar, giving a bitter taste.
