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 Marmalade
Ingredients
Directions
Prepare the quinces
Pare, core, and quarter the quinces.
Boil the cores and peels in enough water to nearly cover them until soft.
Strain the juice from the boiled cores and peels.
Cut out the hard portions from the fresh quinces and simmer them gently until very soft.
Press the quinces through a coarse sieve with the juice.
Make the marmalade
In a clean pan, boil the mixture until it forms a thick paste.
Add three-quarters of a pound of finely powdered sugar for each pound of quinces and half a pint of juice.
Boil the marmalade for half an hour, stirring constantly until it is firm and bright in color.

What each ingredient does
- Quinces
- Provide the pectin and body that let the pulp set into a firm, thick marmalade.
- Sugar
- Sweetens the marmalade and helps it thicken and set as it boils down.
The step that matters
Boiling the thick paste with sugar, stirring constantly. Sugar is added to concentrated fruit pulp, and constant stirring prevents scorching on the base of the pan while the mixture thickens. Sugar concentration and boiling time together determine whether the marmalade sets firm rather than staying runny.
