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 ↓
Molasses Candy
Ingredients
Directions
Prepare
Heat a kettle until hot and butter it like a cake pan.
Cook the candy
Pour in the molasses and sugar.
Boil briskly for 20 minutes, stirring constantly.
Test by dropping a little in cold water; if it solidifies, it's done. If not, boil longer.
Before pouring out, stir in the baking soda.
Add walnut meats or pounded popcorn if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides the main body, dark color and rich flavor of the candy.
- Sugar
- Adds sweetness and helps the mixture harden as it cooks down.
- Baking soda
- Releases gas when stirred into the hot syrup, lightening the candy's texture.
The step that matters
Testing for doneness. Boiling too briefly leaves the syrup too soft to set, while overcooking makes it brittle. A drop in cold water shows whether the sugar has reached the hardening stage.
Swap the walnut
The recipe marks walnut as optional. How well each one fits the dish's main ingredients (molasses, sugar):
- Almondfits better
- Chestnutfits better
- Beansfits better
- Walnutthe original
Fit is the average pairing score against molasses, sugar. Candidates are from the same food group and used in at least 100 recipes.
