To Preserve Quinces
Ingredients
Directions
Make the pippin jelly
In a pot, bring 2 quarts of water to a boil.
Add the sliced pippins and boil covered until the water becomes thick jelly.
Preserve the quinces
Scald the quinces in the boiling water.
For every pint of pippin jelly, add 1 pound of sugar and boil, skimming off any foam.
Add whole quinces to the syrup and boil quickly, or add halved quinces separately.
Test the syrup for jelling by placing a small amount in a glass before removing from heat.

What each ingredient does
- Fair golden pippins
- Their pectin turns the cooking liquid into a jelly that helps the syrup set.
- Sugar
- Sweetens the fruit and, at high concentration, helps preserve it and thicken the syrup.
- Quinces
- Firm fruit that absorbs the syrup and becomes tender as it simmers.
The step that matters
Testing the syrup for jelling. Testing a small sample in a glass shows whether the syrup has reached a set. Pectin and sugar must reach the right concentration to gel; too little cooking leaves it runny, too much can turn it stiff. Check before removing from heat.
