Why it works: Vinegar and sugar 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 ↓
Vinegar Toffee
Ingredients
Directions
Melt the margarine in a saucepan.
Add the sugar and vinegar, then boil slowly while stirring constantly.
Continue boiling until the mixture forms a soft ball when dropped into a cup of cold water.
Grease an enamel or tin plate, pour the toffee onto it, and cut into sections as it begins to set.

What each ingredient does
- Vinegar
- Adds acidity that gives the toffee its sharp, tangy flavour.
- Margarine
- Adds fat, which gives the toffee a smooth, rich texture.
- Brown sugar
- Provides sweetness and forms the bulk of the toffee as it cooks down.
The step that matters
Boiling to the soft-ball stage. Sugar syrup sets according to its temperature and water content. Stopping too early leaves the toffee sticky, while boiling too long makes it hard and brittle. Testing by dropping a little into cold water shows when it has reached the right stage.
