Why it works: Pear and quince match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 133 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Pear, and Quince
Ingredients
Directions
Stew the fruit
Combine pears and water in a brass vessel.
Stew for about an hour until it becomes jam.
Sweeten and finish
Add brown sugar only after the fruit has softened.
Stir constantly after adding sugar.
Transfer the marmalade into jars once it is done.
Cool and seal
Allow to cool completely before sealing the jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pears
- Provide the bulk of the fruit pulp and mild, fresh sweetness.
- Quinces
- Add natural pectin, helping the marmalade set as it cools.
- Brown sugar
- Sweetens the fruit and, as it cooks down, helps thicken it into a preserve.
The step that matters
Adding the sugar after the fruit has softened. Sugar added to firm fruit slows its softening and can leave it tough. Once the fruit is soft, sugar dissolves easily and concentrates as water evaporates. Constant stirring keeps it from sticking and scorching on the base of the pan.
