Why it works: Quince and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 1,444 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Quinces, Preserved
Ingredients
Directions
Prepare the quinces
Pare, core, and quarter the quinces.
Boil in clear water until tender but not broken.
Carefully remove the fruit and discard the water.
Make the syrup and cook
Make a syrup with ½ pound of sugar for each pound of quinces and ⅓ cup of water for every pound of sugar.
Bring the syrup to a boil, then add the fruit.
Cook slowly for an hour until the fruit is bright red and the syrup is jelly-like.
Transfer to glass jars and cover tightly.

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.

What each ingredient does
- Quinces
- Provide the fruit that softens during boiling and turns bright red while cooking slowly in syrup.
- Sugar
- Sweetens the fruit and, as it thickens with cooking, helps the syrup set jelly-like.
The step that matters
Boil the quinces until tender but not broken. Boiling in clear water softens the fruit's firm flesh so it can absorb syrup. Overcooking breaks the pieces apart, while undercooking leaves them too firm to take up sugar evenly.
