Why it works: Sugar and molasses 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
- Light brown sugar
- Provides the sweetness and the deep caramel flavour of the taffy.
- Vinegar
- Adds acidity that helps prevent sugar from crystallising, keeping the taffy smooth.
- Molasses
- Adds moisture, dark colour and a richer, slightly bitter caramel flavour.
- Butter
- Adds fat that gives the taffy a softer, more tender bite.
The step that matters
Cook without stirring. Stirring can agitate the syrup and trigger sugar crystals, which turn the taffy grainy. Cooking undisturbed keeps the syrup smooth until it reaches the thread stage.
