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 float them.
Stew the quinces on the fire until they reduce to a pulp, stirring occasionally to prevent burning.
Pass the pulp through a fine sieve to remove skin and seeds.
Make the marmalade
Weigh the pulp and add ½ lb of broken loaf sugar for each lb of pulp.
Cook the mixture on the fire, stirring constantly until it thickens into marmalade.
To test, drop a little on a cold plate; if it jellies, it's done.
Jar and seal
Pour the hot marmalade into jars, let it cool, and cover with oiled paper.
Seal the jars with bladder or tissue paper brushed with egg white.

What each ingredient does
- Quince pulp
- Provides the fruit body and natural pectin that lets the marmalade set.
- Loaf sugar
- Sweetens the marmalade and helps it thicken and keep as a preserve.
The step that matters
Cooking until the marmalade sets. Stirring constantly keeps the sugar and pulp from scorching on the pan base. Undercooking leaves it runny, while overcooking makes it stiff and dark, so the cold-plate test matters.
