To Preserve Quinces
Ingredients
Directions
Prepare the quinces
Wash and wipe the quinces, then peel and core them.
Cut the quinces into quarters or ½-inch thick slices.
Boil the quinces in scalding water until tender, keeping them covered.
Make the syrup
In a preserving kettle, combine the parings, cores, and seeds with the boiling water from the quinces.
Boil this mixture for an hour, covered.
For every pint of liquid, add 1 pound of loaf sugar and dissolve it.
Bring the sugar mixture to a boil and skim off any scum.
Cook and preserve
Add the quinces and boil until they are red, tender, and clear, but not breaking apart.
Keep the kettle covered to maintain color; add cochineal for improved color if desired.
Once done, remove the quinces and spread them on large dishes to cool.
Boil the syrup again until it resembles a fine jelly.
Pour the hot syrup over the quinces and cover the jars with paper once cooled.

What each ingredient does
- Quinces
- Provide the fruit that turns tender, red and clear as it cooks in syrup.
- Loaf sugar
- Sweetens the fruit and, boiled down, thickens the syrup into a jelly-like set.
- Water
- Carries the quince flavour and pectin from the parings and cores into the syrup.
The step that matters
Boil the quinces until tender but not breaking apart. Quinces need long, gentle cooking to soften and turn red. Rough boiling breaks the fruit apart, while stopping too early leaves it firm and pale.
