Quince Marmalade
Ingredients
Directions
Prepare the quinces
Wash, pare, core, and cut the quinces into small pieces.
In a kettle, place the parings and cores with enough water to cover them and boil slowly until soft.
Make the marmalade
In a porcelain kettle, combine the quinces and sugar.
Strain the liquid from the parings over the quinces and sugar, then cover.
Boil the mixture over a clear fire until smooth and thick, stirring frequently to prevent sticking.
Once cooled, transfer the marmalade to glass jars.

What each ingredient does
- Quinces
- Provide the fruit body and natural pectin that thickens the marmalade as it cooks.
- White sugar
- Adds sweetness and helps set the marmalade into a thick, spreadable texture.
- Quince parings and cores
- Release pectin-rich liquid when simmered, which helps the marmalade gel.
The step that matters
Boil until smooth and thick while stirring frequently. Sugar-rich fruit sticks and scorches on the bottom of the kettle easily. Frequent stirring spreads heat evenly and prevents burning, while cooking until the mixture thickens lets pectin and sugar set properly.
