Why it works: Quince and apple work together. They rank in the top 1% of all ingredient pairs, and cooks put them together in 506 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Quince Jelly
Ingredients
Directions
Prepare the fruit
Wash and wipe the quinces, then quarter, core, and cut them finely.
Quarter, core, and cut the apples finely.
Combine the quinces, apples, and cranberries in a pot.
Add enough water to nearly cover the fruit, then cover and simmer until very soft.
Extract the juice
Turn the mixture into a jelly bag and drain the juice.
Boil the juice for 20 minutes, then measure it.
Make the jelly
Add 1 pint of sugar for each pint of juice.
Once the sugar is dissolved, boil for 5 to 8 minutes or until it jellies.
Pour the jelly into sterilized jars.

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: 1-penten-3-one (fish, pungent).
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
- Quinces
- Provide the bulk of the fruit and natural pectin that helps the jelly set.
- Cranberries
- Add tartness and acidity that balances the sweetness of the sugar.
- Tart apples
- Contribute additional pectin and body to help the jelly firm up.
- Sugar
- Sweetens the jelly and, with the pectin and acid, helps it set.
The step that matters
Boiling the sugar and juice until it jellies. Boil long enough for the sugar and pectin to reach the setting point, but not so long that the jelly becomes overly firm or dark. Checking for a set is what tells you it is ready.
Swap the quince
How well each one fits the dish's main ingredients (apple, sugar):
- Pearfits better
- Vanillafits about as well
- Apricotfits about as well
- Quincethe original
Fit is the average pairing score against apple, sugar. Candidates are from the same food group and used in at least 100 recipes.
