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
Peel, core, and slice quinces when they emit a strong odor, placing them in a preserving pan.
Add enough water to barely cover the quinces and simmer gently until soft, stirring occasionally.
Beat the softened quinces to a pulp with a wooden spoon.
Make the marmalade
Weigh the fruit and add ¾ pound of sugar for each pound of fruit.
Combine the sugar with enough water to moisten it in a preserving pan and boil to a clear syrup.
Add the fruit to the syrup and boil slowly until smooth and thick, stirring frequently.
Check that the marmalade jellies on a plate to determine it is done.
Jar and seal
Pour the hot marmalade into glasses or jars, and cover with paper dipped in egg white once cool.

What each ingredient does
- Quinces
- Provide the pectin and tart flavor that let the fruit set into a firm marmalade.
- Sugar
- Sweetens the fruit and, with boiling, thickens it into a preserve that keeps well.
The step that matters
Checking the set on a plate. Boiling must continue until the mixture is thick enough to jelly when cooled. Stopping too early leaves a runny marmalade, while overcooking can make it stiff and sugary.
