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 ↓
Sugar Candy
Ingredients
Directions
Make the candy
Combine sugar, vinegar, water, butter, and dissolved baking soda in a pot.
Boil the mixture without stirring until it hardens but is not brittle when dropped into cold water.
Flavor with lemon, wintergreen, or peppermint.
Cool and shape
Pour onto buttered plates to cool.
Optionally, pull the candy or cut it into squares once cooled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the candy's sweet base and sets into a hard, glassy texture as it boils.
- Vinegar
- Adds acidity that helps keep the sugar from crystallising into grainy candy.
- Baking soda
- Reacts with the acid to create gas bubbles that lighten the candy's texture.
- Butter
- Adds fat that softens the candy slightly and gives a smoother mouthfeel.
The step that matters
Boil without stirring until it reaches the hard-crack stage. Stirring can trigger sugar crystallisation, leaving the candy grainy. Stopping at the right point matters: too little boiling leaves it sticky, too much makes it brittle and bitter.
