Why it works: Molasses and sugar 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
- Molasses
- Provides the main flavor and dark color, and adds moisture and chewiness to the candy.
- White sugar
- Adds sweetness and, once boiled, helps the candy set firm as it cools.
- Vinegar
- Acidity helps prevent sugar from crystallizing too readily, keeping the candy smoother.
The step that matters
Boiling to the hardening point. Sugar syrup sets according to how much water has boiled off, so the candy hardens only when the mixture reaches the right concentration. Stopping too early leaves it sticky, while cooking too long makes it brittle. Testing by dropping a little into cold water shows when it has reached that point.
