Why it works: Pear and plum match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 245 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ingredients
Directions
Prepare the fruit
Skin, halve, and remove seeds from peaches, pears, and quinces. Remove stones from cherries and leave them in plums.
In a preserving kettle, combine sugar and a lot of water.
Bring the mixture to a boil.
Add the fruit to the boiling syrup and cook until tender.
Heat the jars
Prepare a kettle of hot water and a dipper of hot water.
Plunge a glass jar into the hot water.
Drop the metallic top into the dipper of hot water.
Ensure the jar is heated inside and out to prevent breaking.
Pour the hot water from the jar into the kettle.
Fill and seal
Stand the jar in hot water and fill it with hot fruit and syrup to the brim.
Take the hot cover from the dipper and screw it on tightly.
Turn the jar upside down briefly to check the seal.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the fruit and, with water, forms the syrup that fills the jar.
- Peaches
- Provide the main fruit, softening and taking on flavor as they cook in the syrup.
- Pears
- Provide the main fruit, softening as they cook in the syrup.
- Quinces
- Provide the main fruit, which becomes tender when cooked in the syrup.
The step that matters
Heating the jar inside and out. A cold or unevenly heated glass jar can crack when hot fruit and syrup are poured in, because sudden temperature differences stress the glass. Heating it fully before filling reduces that risk.
Swap the quince
How well each one fits the dish's main ingredients (peach, pear, plum, sugar):
- Apricotfits better
- Vanillafits better
- Applefits better
- Quincethe original
Fit is the average pairing score against peach, pear, plum, sugar. Candidates are from the same food group and used in at least 100 recipes.
