The other day when I was learning to can venison I had enough meat left over to fill approximately another 3 pints but I didn't know if you have to have a full batch of jars inside the canner or not in order to can. I went ahead and wrapped the extra meat and placed it in the freezer for future stew meat. I figure a person probably would only want to completely fill the canner for saving on both time and expense of gas or electricity but is there anybody here who does can only a few cans at a time of something? Would it be worth the effort if a person made a big batch of stew, chili, beans, etc. for dinner and then canned the leftovers for future use?
