To Preserve Quinces
Ingredients
Directions
Prepare the quinces
Place quinces in a stone jar with water and pack with sugar.
Cover the jar and set it in a cool oven until the quinces turn red.
Make the marmalade
In a preserving pan, combine fruit syrup and quince juice.
Boil the mixture until the marmalade is complete, breaking lumps with a ladle.
For whole or half quinces, boil slices of golden pippins in boiling water until it becomes a thick jelly.
Add 1 pound of sugar for every pint of pippin-jelly.
Boil the pippin-jelly mixture.
Skim the mixture to make it clear.
Add whole quinces to the syrup and boil fast.
For halved quinces, skim and test the syrup for jelliness before removing from heat.

What each ingredient does
- Quinces
- Provide the fruit body and natural pectin that help the marmalade set.
- Sugar
- Sweetens the marmalade and, when boiled, helps it thicken into a set jelly.
The step that matters
Testing the syrup for jelliness before removing from heat. Quinces are high in pectin, but the syrup must reach the concentration needed to gel. Removing it too early leaves a runny marmalade, while boiling too long can make it stiff and dull in flavour.
