To Preserve Whole or Half Quinces
Ingredients
Directions
Make the pippin jelly
Add sliced golden pippins to 2 quarts of boiling water in a pot.

What each ingredient does
- Golden pippins
- Their pectin-rich juice forms the jelly base that helps the preserve set.
- Quinces
- Their natural pectin helps the fruit set and gives the preserve body.
- Sugar
- Sweetens the preserve and helps it set into a firm jelly as the syrup thickens.
The step that matters
Testing for set before removing from heat. Pectin and sugar concentration determine whether the preserve sets. Removing it too early leaves it runny, while overcooking makes it stiff and tough. A small test sample shows when the jelly point has been reached.
