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, forms the hard candy structure.
- Butter
- Adds fat and richness, giving the candy a smooth, tender bite.
- Molasses
- Adds depth of flavour and colour, and some moisture, to the candy.
The step that matters
Boiling to the candy stage. Sugar concentration rises as water evaporates, and the final texture depends on how high the temperature goes. Stopping early leaves a soft, sticky result, while going too far makes it hard or burnt. Judge the stage carefully rather than by time alone.
