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
Gather quinces on a dry day and wash them.
Quarter the quinces without peeling them.
Make the pulp
Place them in a pot with just enough water to stew.
Once soft, rub the quinces through a sieve to obtain pulp.
Cook the marmalade
For each pound of pulp, add a pound of brown sugar.
Cook the mixture over low heat, stirring constantly for one hour.
To test, take a small amount and cool it; if it cuts smooth, it's done.

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 pectin and body, so the pulp thickens and sets into a firm marmalade.
- Brown sugar
- Adds sweetness and helps the pulp thicken and set while also preserving it.
The step that matters
Cooking over low heat with constant stirring. The pulp thickens as it cooks and the sugar can scorch on the bottom of the pot, so constant stirring over low heat prevents burning. The cool test shows whether enough pectin and sugar have gelled to set.
