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
Cook the sugar
In a large saucepan, combine the sugar, butter, vinegar, and water.
Heat the mixture until it begins to thicken, then add the hickory nuts.
To test the candy, quickly take a small amount from the center and drop it into cold water.
Remove from heat when the candy particles are brittle.
Set and cool
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 base and provides most of the sweetness as it cooks and sets.
- Butter
- Adds fat for a richer flavor and a softer bite in the finished candy.
- Vinegar
- Adds acidity that helps keep the sugar from crystallizing into a grainy texture.
- Hickory nut kernels
- Provide crunch and a rich, nutty flavor throughout the candy.
The step that matters
Removing the candy at the brittle stage. Sugar hardens as its temperature rises. Removing it too early leaves the candy sticky, while cooking it too long makes it hard, dark, and possibly bitter. The cold water test shows when it has reached the right stage.
