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 ↓

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 taffy.
- Sugar
- Adds sweetness and, once boiled, helps the taffy set firm.
- Vinegar
- Dissolves the sugar and adds acidity that softens the texture of the candy.
- Butter
- Adds fat that makes the taffy tender and easier to pull.
- Baking soda
- Reacts with the acid in the vinegar and molasses, lightening the color and making the candy tender.
The step that matters
Boil until it hardens when dropped into water. Sugar candy sets according to how much water has boiled off. Too little boiling leaves the taffy sticky, while too much makes it brittle, so the drop test helps judge the right point.
“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.
