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
Dissolve the sugar in the vinegar.
Mix the sugar-vinegar mixture with the molasses and boil, stirring frequently, until it hardens when tested in cold water.
Stir in the butter and baking soda (dissolved in a little hot water).
Give one hard final stir and pour onto buttered dishes.
Shape and cut
Work with buttered hands to pull into long sticks and place on dishes.
Once cold, it can be easily cut.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Forms the bulk of the candy and gives it its dark color and rich flavor.
- Sugar
- Adds sweetness and, when boiled with the molasses, helps the candy set firm as it cools.
- Baking soda
- Reacts with the acidic vinegar to release gas, lightening the candy's texture.
- Vinegar
- Acidifies the mixture, helping to dissolve the sugar and softening the final texture.
- Butter
- Adds fat for a smoother, less brittle texture and keeps the candy from sticking.
The step that matters
Boiling until it hardens in cold water. Sugar candy sets according to how far its water has boiled off. Stopping too early leaves a soft, sticky candy, while boiling too long makes it brittle or scorched. Testing a small drop in cold water shows when it is ready.
