When the processing time is over, remove the jars from the bath and set them in a place where they will be undisturbed for 12 to 24 hours. This is always my favorite part because you can hear the occasional POP! POP! of the lids as they seal. If after 24 hours you are able to push on the lid and it goes up and down, it is not sealed. You can either refrigerate the unsealed ones and use the jam within three weeks, or you can reprocess in the canner with a new lid.
And I hope this jam is gonna last
After jam is cooled and jars are sealed, wipe off the jars, label them, and then store them in a cool, dark place. The jam is good for up to a year.
I hope you like jammin' too
