Quince Marmalade
Ingredients
Directions
Prepare the quinces
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.
Use ½ pint of juice for each pound of fresh quinces, cutting out any hard parts around the cores.
Make the marmalade
Simmer the quinces gently until perfectly tender, then press them with the juice through a coarse sieve.
In a clean pan, boil the mixture until it forms almost a dry paste.
Add ¾ lb of powdered sugar for each pound of quinces and the ½ pint of juice, then boil for 30 minutes, stirring continuously.

What each ingredient does
- Quinces
- Provide the fruit pulp that softens, thickens and sets into the marmalade.
- Powdered sugar
- Adds sweetness and, as it boils down, helps the marmalade thicken and set.
The step that matters
Boiling the pulp to a dry paste with continuous stirring. Quince pulp is thick and sugars scorch easily on the base of the pan. Constant stirring spreads heat evenly and prevents burnt flavour, while the long reduction concentrates the pectin and sugar so the marmalade sets.
