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 quince
Peel and slice the quinces.
Stew them gently in enough water to prevent burning until soft.
Rub the softened quinces through a fine sieve into a preserving pan.
Make the marmalade
Add 1 pound of sifted lump sugar for each pound of quince.
Boil the mixture for about 10 minutes, stirring constantly.
Test for doneness by placing a drop on a plate; if it sets in a minute or two, it's done.
If not, boil a little longer.
Jar and store
Cover the jars with brandy-dipped paper.
Tie the paper down.
Store the jars in a dry room.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Quinces
- Provide the pectin and tart flavour that give the marmalade its body and set.
- Sifted lump sugar
- Sweetens the marmalade and helps it thicken and set as it boils.
The step that matters
Testing for doneness. Sugar and fruit pectin only set at the right concentration. Boiling too briefly leaves the marmalade runny, while overboiling can make it stiff and dull. A cold plate test shows whether it has reached a set.
