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 fruit
Pare, core, and quarter the quinces, then boil them in enough water to nearly cover them until they begin to break.
Strain the juice from the quinces and set aside.
Cook the quince
Simmer the remaining quince pieces gently until perfectly tender, then press them with the juice through a coarse sieve.
In a clean pan, combine the quince mixture and boil until it forms almost a dry paste.
Make the marmalade
Add 3/4 lb of powdered sugar for each pound of quinces and the half pint of juice, then boil for 30 minutes, stirring continuously.
For a richer marmalade, use equal weights of fruit and sugar and boil for a shorter time.

What each ingredient does
- Quinces
- Supply pectin and tart flavour that help the marmalade set.
- Powdered sugar
- Sweetens the marmalade and, as it thickens, helps it set firm.
- Quince juice
- Adds extra pectin and moisture, helping the fruit cook down to a set mass.
The step that matters
Boiling with the sugar. Once sugar is added, the mixture can scorch on the bottom of the pan, so constant stirring is needed. The sugar and pectin must also cook long enough together to thicken into a set marmalade.
