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 Nut Candy
Ingredients
Directions
Make the candy
Combine the sugar, butter, vinegar, and water in a thick saucepan.
Heat the mixture until it begins to thicken, then add the nuts.
To test the candy, quickly take a small amount from the center and drop it into cold water.
Remove from heat as soon as the candy particles become brittle.
Set
Pour the mixture into buttered plates to cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White sugar
- Forms the candy's sweet, crisp structure as it cooks and hardens.
- Vinegar
- Acidity slows sugar crystallization, helping the candy stay smooth and brittle.
- Butter
- Adds fat that softens the candy's texture and richness.
- Hickory nuts
- Add crunch and nutty flavor throughout the candy.
The step that matters
Removing from heat at brittleness. Sugar keeps darkening and hardening as it cooks, so removing the mixture too late can burn it or make it overly hard. Testing a small drop in cold water shows when it has reached the brittle stage.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, vinegar, butter):
- Almondfits better
- Sesamefits better
- Soybeanfits better
- Nutsthe original
Fit is the average pairing score against sugar, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
