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 pulp
Slice the quinces and place them in a preserving pan with enough water to cover them.
Stew the quinces over low heat, stirring occasionally, until they reduce to a pulp.
Pass the pulp through a fine sieve to remove the skin and seeds.
Make the marmalade
Weigh the pulp and add 5 lb of sugar for every lb of pulp, breaking the sugar into small pieces.
Cook the mixture over low heat, stirring constantly, until it thickens into a marmalade.
To test, drop a little on a cold plate; if it jellies, it's done.
Jar and cover
Pour the hot marmalade into jars.
Let it cool.
Cover with oiled paper cut to size.
Optionally, cover the tops with bladder or tissue paper brushed with egg white.

What each ingredient does
- Quince pulp
- Provides the fruit body and natural pectin that helps the marmalade thicken and set.
- Loaf sugar
- Sweetens the marmalade and, cooked down with the fruit, helps it gel and keep well.
The step that matters
Testing for the set. Sugar and fruit pectin form a gel only at the right concentration. Stop cooking too early and the marmalade stays runny; cook too long and it turns stiff, so the cold-plate test matters.
