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 water, sugar, isinglass, and gum-arabic in a brass or preserving kettle.
Bring to a boil, then remove from heat and skim off any foam.
Return to heat and boil until the mixture becomes brittle when dropped in cold water.
Flavor and shape
If using white sugar, add a little vinegar to prevent excessive brittleness.
Add your preferred flavoring and coloring if desired.
If adding nuts or cocoa-nut meats, include them before pouring out the mixture.
Shape the candy as you like.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the bulk of the candy and, when boiled down, sets into a brittle, glassy texture.
- Isinglass
- Gelatin-like protein that adds body and helps the candy set with a firm, tender texture.
- Gum-arabic
- Stabilizes the syrup and helps keep the candy smooth and resistant to crystallizing.
- Water
- Dissolves the sugar so it can be boiled into a syrup evenly.
The step that matters
Boiling until brittle. The syrup must reach the hard-crack stage: when dropped in cold water it should snap. Stopping early leaves a sticky candy, while overcooking can make it bitter or too hard.
Swap the nuts
The recipe marks nuts as optional. How well each one fits the dish's main ingredients (sugar, vinegar):
- Sesamefits better
- Chestnutfits better
- Soybeanfits better
- Nutsthe original
Fit is the average pairing score against sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
