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 ↓
To Make Molasses Candy
Ingredients
Directions
Prepare
Grease a saucepan with butter.
Add molasses and brown sugar to the saucepan.
Cook
Boil for 30 minutes, stirring continuously.
When the mixture becomes brittle, it is done.
If desired, add nuts just before removing from heat.
Set
Pour the mixture into buttered tin pans and let cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides the main sweetness and deep flavor, and its sugars harden into a firm candy as water boils off.
- Brown sugar
- Adds sweetness and a caramel-like flavor, and helps the candy set firm as the mixture thickens.
The step that matters
Testing for brittleness. As the mixture boils, water evaporates and the sugar becomes more concentrated, so the candy hardens. Judging doneness by brittleness rather than time alone prevents a sticky, underset candy or one that scorches.
Swap the nuts
The recipe marks nuts as optional. How well each one fits the dish's main ingredients (butter, molasses, sugar):
- Almondfits better
- Pecansfits about as well
- Walnutfits about as well
- Nutsthe original
Fit is the average pairing score against butter, molasses, sugar. Candidates are from the same food group and used in at least 100 recipes.
