Why it works: Apple and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 16,478 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Apple Jelly
Ingredients
Directions
Make the juice
Boil the apples in water until soft.
Strain the mixture through a linen sack without squeezing.
Make the jelly
Add 1 pound of sugar for every pint of juice.
Boil the sugar and juice together for 15 to 20 minutes.
Skim the mixture until clear.
Test the jelly by dropping it into a tumbler of cold water; if it falls in a mass, it is done.
Jar and store
Pour into jelly cups, cover when cool, and store in a cool place.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: beta-damascenone (apple, rose).
Apple and sugar barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tart apples
- Provide the pectin and acid that let the juice set into a jelly.
- White sugar
- Adds sweetness and helps the jelly set and keep its texture.
The step that matters
Testing the set. Apple juice gels only when enough pectin, acid and sugar are concentrated by boiling. Stopping too early leaves a runny jelly, while boiling too long can make it stiff, so the cold-water test shows when it is ready.
