Q: I made a lot of jam. I sterilized the jars and heated the lids. All the jars are sealed and I put paraffin wax on top of the jam, but I think I may have moved them too soon after they sealed. I just checked my jars today and quite a few have an air bubble on the side of the jar (just one), not lots of bubbles. Is this dangerous?
Can the jars be kept or should they be used right away? I was going to give as gifts, now I am afraid to do so.

Editor: Most jams need to be processed in a hot water bath after you put the lids on. If you did this, then you should probably be fine even with a few air bubbles. If not, best to gift, use, or freeze the jam sooner rather than later!
Readers, any advice on this?
