This is probably not the right place to post this but I need an answer. My daughter canned some salmon the other day. She used quart jars and only filled them between 1/2, 1/3, to 2/3 full. What I've read is you want to pack the salmon tight and only leave about a 1/2 inch to 1 inch of airspace at the top. The canning process is supposed to pull a vacuum but if you have too much airspace that is not going to happen. I'm afraid her salmon is ruined. I don't want her to get sick. So, does anyone know if canning this way will work or should she get rid of the stuff she's already canned? Thanks
