Why it works: Sugar and quince 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
Make the pippin jelly
Boil 2 quarts of water in a pot.
Add sliced golden pippins, cover, and boil until the water becomes a thick jelly.
Cook the quinces in syrup
Scald the quinces in the boiling water.
For every pint of pippin jelly, add 1 pound of sugar and boil, skimming off any foam.
Add whole quinces to the syrup and boil quickly; for halved quinces, boil separately.
Test the syrup for jelling before removing from heat.

What each ingredient does
- Quinces
- Provide the fruit and flavor that the preserve is built around.
- Golden pippins
- Release pectin into the water, helping the syrup thicken into a jelly.
- Sugar
- Sweetens the preserve and helps it set into a thick, spreadable texture.
The step that matters
Test the syrup for jelling before removing from heat. Syrup that is removed too early stays runny, while overcooking can make it stiff or sugary. Pectin and sugar set only at the right concentration, so a test confirms the point of setting before the pot comes off the heat.
