Reprocessing Unsealed Jars

If a lid fails to seal on a jar, remove the lid and check the jar-sealing
surface for tiny nicks. If necessary, change the jar, add a new, properly
prepared lid, and reprocess within 24 hours using the same processing time.
Headspace in unsealed jars may be adjusted to 1-1/2 inches and jars could be
frozen instead of reprocessed. Foods in single unsealed jars could be stored in
the refrigerator and consumed within several days.
