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 juice
Fill a kettle with refuse quinces, parings, cores, and seeds, and cover with water.
Add 6 sour apples to each gallon of quinces.
Boil all together, then strain the juice through a flannel bag.
Make the jelly
For every quart of juice, add 1 pint of sugar.
Boil rapidly until the mixture drops short from the spoon.
Heat the glasses and fill them with the jelly.

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 main fruit flavour and natural pectin that helps the juice set into jelly.
- Sour apples
- Add extra pectin and acidity, supporting the jelly's set and bright flavour.
- Sugar
- Sweetens the juice and, with boiling, helps the jelly set and keeps it preserved.
The step that matters
Boil rapidly until the mixture drops short from the spoon. Boiling concentrates the juice and sugar until pectin and acid can form a gel. Under-boiling leaves a runny jelly, while overboiling can make it stiff or caramelised.
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.
