How to Tell When the Jam and Jellies are Done
When you’re finished processing, remove the canning rack or use tongs to remove jars. Set them on towels or rack at least 1" apart. Cool completely for 12 to 24 hours. To test the seal, press the center of each lid. If the “dip” in the lid holds, the jar is sealed. If it bounces up and down, it isn’t sealed. You may refrigerate unsealed jars and use them within 3 days; freeze them; or reprocess them in clean jars and new lids.
