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
Make the candy
Combine molasses, brown sugar, and butter in a six-quart kettle.
Boil over a low fire, stirring often to prevent burning, until thick.
Test by dropping a few drops into cold water; it should harden quickly and break easily.
Add baking soda and stir well.
Pour into well-buttered flat tins.
Pull and shape
When partly cooled, butter your hands.
Pull and double the candy until it turns a whitish yellow. Mix while pulling.
Cut into strips and roll or twist as desired.
If using flavoring, add it on top as it cools.

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 deep sweet flavor of the candy.
- Brown sugar
- Adds sweetness and helps the candy set firm as it cooks.
- Butter
- Adds fat for a smoother, less brittle texture and helps prevent sticking.
- Baking soda
- Reacts with the hot syrup to add air, lightening the color and texture for pulling.
The step that matters
Testing the candy in cold water. Cooking must reach the right thickness: if the candy is undercooked it stays sticky, and if overcooked it becomes hard and brittle. A cold-water drop test shows whether it hardens quickly and breaks cleanly, indicating the sugar has reached the correct concentration.
