To Preserve Quinces Whole
Ingredients
Directions
Poach the quinces
Pare the quinces very thin and place them in a preserving pan with the parings.
Cover the pan with a plate to keep in steam.
Fill the pan with water.
Heat until the quinces are soft and pink.
Make the syrup
Boil 1½ pounds of sugar with 1 pint of the water used for boiling the quinces to make a thin syrup.
Remove the scum from the syrup.
Add the quinces to the syrup.
Boil the quinces for 10 minutes.
Remove the pan from heat.
Let the mixture cool overnight.
Finish and pack
The next day, boil the quinces until they look clear.
Transfer the quinces to a dish.
Add the remaining sugar to the syrup.
Boil until the syrup is thick.
Return the quinces to the syrup.
Boil once more until the quinces are clear and a fine color.
Pack the quinces into deep jars.
Seal the jars with a bladder.
Optionally core the quinces with an apple scoop or cut them in half, but they look better whole with the stalks on.

What each ingredient does
- Quinces
- Provide the fruit that softens, turns pink and sets clear in the syrup.
- Lump sugar
- Sweetens the fruit and, boiled down, thickens the syrup and preserves the quinces.
- Sugar
- Sweetens the syrup in two portions, building thickness as it reduces.
The step that matters
Boil the quinces until they look clear. Slow simmering in syrup lets sugar gradually replace the water in the fruit, so it turns clear and keeps. Boiling too hard or too briefly can break the fruit or leave it cloudy and unpreserved.
