Why it works: Sugar and vinegar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 20,806 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Ingredients
Directions
Cook the candy

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides the sweetness and, as it cooks, the hard glassy structure of the candy.
- Butter
- Adds fat for a rich flavour and a smoother, less brittle bite.
- Vinegar
- Adds acidity that helps keep the sugar from crystallising into grainy pieces.
- Baking soda
- Reacts with the acid to form small gas bubbles that lighten the texture.
The step that matters
Testing for doneness. Sugar sets hard only after enough water has boiled off. Stopping too early leaves the candy soft and sticky, while cooking too long can scorch the sugar and make it bitter. The hot-water drop test shows whether it has reached the crisp stage.
