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
Prepare the apples
Quarter the apples without peeling or coring them.
Place them in cold water.
Put the apples in a preserving kettle.
Simmer gently until the juice flows freely.
Boil slowly until the apples are tender and broken.
Pour the mixture into a flannel jelly bag.
Let the juice drip through without squeezing.
Make the jelly
Measure the juice.
Add 1 pound of granulated sugar for each pint of juice.
Heat the sugar in the oven.
Return the juice to the fire and boil for 20 minutes.
Skim the mixture.
Stir in the heated sugar until dissolved.
Bring to a boil again.
Remove from heat.
Fill and set
Set jelly glasses on a wet cloth to prevent cracking.
Fill them immediately.

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, juicy apples
- Provide the juice and natural pectin that set the jelly.
- Granulated sugar
- Sweetens the jelly and helps it set to a firm, clear texture.
The step that matters
Stir in the heated sugar until dissolved. Sugar must fully dissolve so it does not form crystals in the jelly. Heating the sugar first helps it dissolve quickly without cooling the boiling juice, which keeps the set even.
