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 bulk of the candy and its dark, rich flavor.
- Sugar
- Adds sweetness and helps the mixture set firm as it cooks and cools.
- Butter
- Adds fat for a smoother, less brittle texture and richer flavor.
The step that matters
Boiling until the cold-water test shows a hard set. Candy sets according to how much water has boiled off, which raises the sugar concentration. Stopping too early leaves a soft, sticky result, while cooking too long makes it hard and brittle. Checking a small drop in cold water shows when the mixture has reached the right concentration.
Swap the walnut
How well each one fits the dish's main ingredients (molasses, sugar, butter):
- Almondfits better
- Pecansfits about as well
- Walnutthe original
- Chestnutfits about as well
Fit is the average pairing score against molasses, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
