To Preserve Whole or Half Quinces
Ingredients
Directions
Make the pippin jelly
Combine boiling water and sliced pippins in a pot.
Boil covered until the water thickens into a jelly.
Preserve the quinces
Scald the quinces.
For every pint of pippin jelly, add 1 pound of sugar and boil, skimming until clear.
Add whole quinces to the syrup and boil quickly.
For halved quinces, boil separately.
Test the syrup for jelling by placing a small amount in a glass before removing from heat.

What each ingredient does
- Quinces
- Provide the fruit that is cooked and preserved, becoming tender and flavorful in the syrup.
- Sugar
- Sweetens the preserve and helps the syrup thicken and set as it cooks.
- Pippins
- Release pectin into the boiling water, forming the jelly that the preserve syrup is built on.
The step that matters
Testing the syrup for jelling. Sugar syrup thickens as water evaporates and sets when it reaches the right concentration. Testing a small amount in a cold glass before removing from heat shows whether it will gel, so the cook avoids under- or overcooking.
