Oops! The lids didn’t seal! I used the wrong pressure! Can these jars be saved?
Home canned foods can be reprocessed within 24 hours of initial processing. Remove the lid and replace with a new lid. Change jars if the necessary because of nicks in the jar rim. Reprocess the food using the proper procedures for that food.
Another option is to store the jars in the refrigerator and use within a few days or freeze for later use. If freezing, be sure to have at least 1 1/2 inches headspace for expansion.
Do not use jars of food that become unsealed during storage for an unknown reason.
