To Make Quince Marmalade
Ingredients
Directions
Prepare the quince
Cut the quinces into quarters and remove the cores.
Place the quince quarters in a preserving pan.
Cover the pan with the quince peels.
Fill the pan with water.
Place a plate on top of the pan to trap steam.
Stew over low heat until the quinces are tender and pale pink.
Strain the cooking water.
Remove the peels from the strained water.
Mash the quince quarters into a pulp using a mortar.
Make the marmalade
For every pound of quince, add one pound of lump sugar.
Melt the sugar with a little of the reserved cooking water.
Bring the mixture to a boil.
Skim off any foam that rises to the surface.
Add the quince pulp to the boiling mixture.
Boil gently for 30 minutes.
Stir constantly to prevent burning.
Pot and seal
Transfer the marmalade to flat pots.
Cover the pots with brandy papers.

What each ingredient does
- Quinces
- Provide the fruit pulp that sets into the marmalade's body and gives its flavour.
- Lump sugar
- Sweetens the marmalade and helps it thicken and set as it boils down.
- Water
- Softens the quinces during stewing and creates the cooking liquid for the syrup.
The step that matters
Stir constantly while boiling. Sugar-rich mixtures scorch easily on the base of the pan as water evaporates. Constant stirring spreads the heat evenly and prevents burnt flavour and sticking.
