To Preserve Whole or Half Quinces
Ingredients
Directions
Make the syrup
In a pot, bring 2 quarts of water to a boil.
Add the sliced golden pippins and cover the pot.
Boil quickly until the water turns into a thick jelly.
Cook the quinces
Scald the quinces and add them to the syrup.
For whole quinces, add them all at once; for halved quinces, add them separately.
Boil the syrup rapidly and skim off any foam.
Test the set
To test if the syrup jellies, place a small amount in a glass before removing from heat.

What each ingredient does
- Golden pippins
- Their natural pectin helps the boiled syrup thicken and set into a jelly.
- Sugar
- Sweetens the syrup and helps preserve the fruit while it sets.
- Quinces
- The main fruit, which becomes tender and flavourful as it cooks in the syrup.
The step that matters
Testing the syrup for a set. Pectin and sugar form a gel only at a sufficient concentration. Removing the pot too early leaves runny syrup, while cooking too long can make it stiff, so the cold-glass test shows when it is ready.
