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 ↓
Butter-scotch Candy
Ingredients
Directions
Make the candy
In a large pot, combine brown sugar, butter, vinegar, and water.
Bring the mixture to a boil.
Once boiling, add the baking soda.
Boil for 30 minutes, checking for crispness by dropping a small amount into cold water.
Set and cut
If it hardens, remove from heat and pour into a buttered pan.
Let it cool slightly, then cut into squares.

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 the caramel flavour as the sugar cooks down.
- Butter
- Adds fat and richness, giving the candy a smooth, buttery texture.
- Baking soda
- Reacts with the hot acidic mixture to create bubbles that lighten the candy's texture.
The step that matters
Boil for 30 minutes and test for crispness. Sugar candy sets according to how much water has boiled off and how hot the syrup gets. Testing a drop in cold water shows whether it has reached a hard, brittle stage. Stopping too early leaves the candy soft and sticky, while cooking too long can make it bitter or burnt.
