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
Cook the molasses
Combine molasses, sugar, vinegar, and butter in a saucepan.
Cook over medium heat, stirring until the mixture reaches a boil.
Add baking soda and stir well just before it is done.
Test by dropping a small amount into cold water; if it hardens immediately, it is ready.
Cool and pull
Pour the mixture onto greased plates and set outside to cool.
Begin pulling the candy as soon as possible to prevent it from hardening too much.
Shape and break
Form it into a long stick and break it into short pieces by striking with a knife when cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides the main sweetness, dark color, and deep flavor of the candy.
- Sugar
- Adds sweetness and helps set the candy's firm, brittle texture as it cooks.
- Vinegar
- Adds acidity that helps prevent the sugar from crystallizing and reacts with baking soda.
- Baking soda
- Reacts with the acid to form gas bubbles that lighten the candy's texture.
- Butter
- Adds fat that softens the texture and gives a smoother bite.
The step that matters
Adding the baking soda near the end. Baking soda reacts with the acid and foams vigorously, so it must be stirred in well just before the candy finishes cooking. Adding it too early lets the foam collapse and the candy lose its light texture.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
