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 ↓
To Preserve Quinces
Ingredients
Directions
Prepare the quinces
Peel and cut quinces in halves or quarters, removing the hard parts, and place them in cold water.
Weigh 2-3 pounds of quinces.
Boil the quinces in water over high heat until they start to soften.
Reduce heat and cook the quinces slowly until completely soft.
Remove the quinces and place them on a dish.
Make the syrup and preserve
Weigh an equal amount of sugar.
Make a thick syrup using equal parts clear water and the water from boiling the quinces.
Remove any scum from the syrup.
Add the quinces to the syrup.
Cook the quinces slowly until they are thoroughly coated with sugar.
Repeat the process with additional quinces and syrup until all are preserved.
Store
Once cooled, store the preserved quinces in small jars.
Cover the jars with brandy paper.

What each ingredient does
- Quinces
- Provide the fruit that softens and turns tender and sweet when cooked slowly in syrup.
- Sugar
- Forms a thick syrup that sweetens the fruit and preserves it by drawing out its water.
The step that matters
Cook the quinces slowly until completely soft. Quinces are firm and hard to bite until well cooked. Gentle, slow heat softens the dense flesh evenly without breaking the fruit apart, so it can later absorb the syrup properly.
