Why it works: Quince and lemon match in chemistry and in kitchens. They rank in the top 11% of all ingredient pairs, and cooks put them together in 336 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Quince Preserves
Ingredients
Directions
Core and quarter the quinces, then place them in a preserving kettle and cover with water.
Boil for 30 minutes, then strain through a fine sieve.
Return the juice to the kettle and boil the quinces in it until tender, lifting them out as they are done.
If the liquid is low, add more water.
Once all quinces are cooked, add sugar and boil for 10 minutes.
Add the quinces and boil until they change color, about 1 hour and 15 minutes, without stirring.
Occasionally slide a silver spoon under the quinces to prevent burning.
When packing into jars, add 1-2 thin slices of lemon to each jar.

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).
Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
Swap the quince
How well each one fits the dish's main ingredients (sugar, lemon):
- Orangefits better
- Limefits better

- Quincethe original
Fit is the average pairing score against sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
