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
Gather fully ripe quinces, then pare, quarter, and core them.
Boil the skins with an equal amount of water to the weight of the quinces until soft.
Mash the skins and strain the water, then add it to the quinces.
Boil the quinces until soft enough to mash fine, then rub through a sieve.
Make the marmalade
Add the same weight of sugar to the pulp and stir together.
Cook over gentle heat until it falls from a spoon like jelly; test in a saucer.
If it jellies when cold, pour into pots or tumblers and secure as directed for jelly.

What each ingredient does
- Quinces
- Provide the pectin and tart flavour that give the marmalade its set and character.
- Sugar
- Sweetens the pulp and helps the mixture thicken into a jelly-like set.
- Water
- Extracts pectin from the skins and softens the fruit so it can be mashed and strained.
The step that matters
Testing the set on a saucer. Quince pulp must be cooked until it sets, but overcooking can make it stiff and dull, while undercooking leaves it runny. A cold saucer test shows whether the pectin has gelled enough, since the mixture thickens further as it cools.
