Quince Preserves
Ingredients
Directions
Prepare the quinces
Wash the quinces thoroughly.
Cut the quinces into halves or quarters, removing the cores. Place the cut quinces in cold water.
Weigh the quinces and measure ¾ pound of sugar for each pound of fruit.
Cook the quinces
Steam the quinces over boiling water until they are easily pierced with a fork.
Prepare boiling syrup and add the steamed quinces, cooking until they are clear while skimming off impurities.
If the syrup is not thick enough, boil it longer and pour it over the fruit.
Jar and seal
Transfer the fruit to stone jars.
Seal the jars using self‑sealing lids.

What each ingredient does
- Ripe quinces
- Provide the fruit, pectin and tartness that give the jam its body and flavour.
- Sugar
- Sweetens the jam and, when boiled into syrup, helps it thicken and preserve the fruit.
The step that matters
Cooking the quinces in the syrup until clear. Cooking must continue until the fruit turns clear and the syrup thickens. Undercooked syrup stays thin and may not set, while the fruit needs to be fully softened and its impurities skimmed for a clean, stable jam.
