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, white sugar, vinegar, and butter in a pot.
Boil for 20 to 30 minutes.
Test by dropping a little into cold water; if it hardens, it's ready.
Set and work
Pour into a flat, buttered dish.
Once cool, work the candy with your hands.

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 flavor of the candy.
- White sugar
- Adds sweetness and helps the mixture set firm as it cooks down.
- Vinegar
- Adds a little acidity that helps keep the sugars from crystallizing too quickly.
The step that matters
Testing the boil in cold water. Boiling longer makes the candy harder once cooled, so the cold-water test shows when the sugar has reached the right concentration. Pulling it off too early leaves it soft and sticky, while cooking too long can make it brittle.
