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 into halves or quarters, removing the hard parts, and place them in cold water.
Weigh 2–3 pounds of quinces and boil them in water over high heat until boiling quickly, then reduce heat and cook until soft.
Remove the quinces and place them on a dish.
Make the syrup and cook
Weigh an equal amount of sugar and prepare a thick syrup using equal parts of clear water and the water from boiling quinces.
Remove scum from the syrup, add the quinces, and cook slowly until they are thoroughly coated with sugar.
Repeat the process with additional quinces and new syrup until all are done.
Store
Once cooled, store the quinces in small jars and cover them with brandy paper.

What each ingredient does
- Quinces
- Are the fruit being preserved, providing the main body and flavor of the finished dish.
- Sugar
- Coats the quinces and, in a thick syrup, helps preserve them and gives sweetness.
- Clear water
- Forms the syrup with sugar and quince cooking water, dissolving the sugar for coating the fruit.
The step that matters
Cooking the quinces in the syrup. Cooking slowly lets sugar penetrate the fruit and thoroughly coat it. Rushing with high heat can break the quinces apart or leave the sugar on the surface, so the fruit does not preserve well.
