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 ↓
Sugared Quinces
Ingredients
Directions
Prepare the quinces
Wipe the quinces with a wet cloth, then peel, core, and cut them into eighths.
Place the cores and parings in a small cloth bag and boil them with the quinces in a preserving kettle covered with boiling water.
Boil gently until the quinces are tender, then drain and cool them.
Pack with sugar
Weigh the cooled quinces and use an equal amount of granulated sugar.
Layer the quinces and sugar in glass or earthen jars, then cover the jars airtight.
Check and scald
Check the jars frequently for signs of fermentation.
If fermentation is present, place the jars in a large pan of warm water, loosen the covers, and heat the water until the quinces are scalding hot.
Seal the jars airtight again after the quinces are scalded.

What each ingredient does
- Quinces
- Provide the fruit that becomes tender and sweet, forming the body of the preserve.
- Granulated sugar
- Adds sweetness and helps preserve the fruit by drawing out moisture.
The step that matters
Checking the jars for fermentation. Sugared fruit can ferment if air or wild yeasts get in. Checking often lets you catch fermentation early, and scalding the quinces kills the microbes that cause it before the jars are resealed.
