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
The book gives no oven temperature. The 250°F in the steps was added when the recipe was transcribed, as a starting point.
Make the candy
In a large pot, combine the sugar, water, and vinegar.
Bring the mixture to a boil over medium heat, stirring until the sugar dissolves.
Add the butter and continue to boil until the mixture reaches the hard ball stage (about 250°F or 121°C).
Stir in the hickory nuts and mix well.
Set and break
Pour the mixture onto a greased surface and let it cool before breaking into pieces.

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, crystalline structure as the syrup cooks and hardens.
- Butter
- Adds fat and richness, giving the candy a smoother, less brittle bite.
- Hickory nuts
- Provide crunch and a rich, nutty flavor throughout the candy.
- Vinegar
- Adds a little acidity that helps prevent the sugar from recrystallizing into grainy candy.
The step that matters
Boiling to the hard ball stage. Sugar syrup must reach about 250°F (121°C) to set firm when cooled. Stopping early leaves it sticky, while overcooking makes it brittle or scorched.
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.
