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
- New orleans molasses
- Adds deep sweetness, dark color, and a rich, slightly bitter flavor.
- Butter
- Adds fat for a rich flavor and a smoother, less brittle bite.
- Powdered sugar
- Provides sweetness and the sugar that hardens into the candy as it cooks.
- Baking soda
- Reacts with the acid in molasses, releasing gas that lightens the candy's texture.
The step that matters
Boiling until it hardens in cold water. Sugar candy sets according to how far its water has boiled off. Stopping too early leaves it soft and sticky, while cooking too long scorches the sugars and turns the candy bitter.
