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 molasses
Pour in 1 quart of molasses and 1 cup of sugar.
Boil briskly for 20 minutes, stirring constantly.
Test by dropping a little into cold water; if it solidifies, it's done. If not, boil longer.
Before pouring out, stir in 1 teaspoon of powdered soda.
Optionally, add walnut meats or pounded popcorn for improvement.

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 set firm when cooled.
- Powdered soda
- Reacts with the hot syrup to lighten its texture and make it brittle.
The step that matters
Testing for doneness in cold water. Sugar syrup firms as its temperature rises and water evaporates. A small drop in cold water shows whether it has boiled long enough to set, so checking prevents a sticky or soft candy.
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.
