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 ↓
Quince Preserves
Ingredients
Directions
Make the syrup
Boil 4 cups water with 4 cups sugar until it boils.
Skim off any foam.
Cook the quinces
Quarter the quinces if large; otherwise, halve them.
Add the quinces to the syrup and cook slowly until they are tender.
Remove the quinces.
Continue boiling the syrup until it thickens, but do not overboil to avoid darkening.
Jar and store
Strain the syrup over the quinces in jars and seal them.
Store in a cool, dark place.

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 flavor and natural pectin that helps the syrup thicken and set.
- Sugar
- Sweetens the preserve and, as it concentrates while boiling, thickens the syrup and helps preserve it.
The step that matters
Stop boiling the syrup once it thickens. Prolonged boiling caramelizes the sugar, which darkens the syrup and can give it a burnt, bitter flavor. Watch closely as it thickens and stop in time.
