TO CAN QUINCES

Quinces can be peeled and sliced up to 2 hours ahead if held in acidulated water (1 tablespoon lemon juice per quart of water) to prevent oxidation. Drain thoroughly before cooking. The finished preserve, if processed using modern canning methods with proper headspace and processing time, can be made months in advance.

If following this historical method without proper canning procedures, refrigerate immediately and consume within 2 weeks. For modern preservation, process filled jars in a boiling water bath for 20 minutes (adjusting for altitude), then store sealed jars in a cool, dark place for up to 1 year. Refrigerate after opening and use within 3 weeks.
