I don't can much now because I am alone. When we lived in Oregon I nearly canned myself crazy as there was so much wonderful produce and salmon. To the lady with the glass top stove, we use to can in a sheltered outside area with a three burner Coleman stove. It worked fine. We would go to coast in our rv and can in the campground. Nothing like homecanned tuna and salmon. Used a small 7 qt pressure cooker. I have one that will do 24 quarts. Left it at home but it comes in handy for greenbeans, etc. Quit freezing much as have had too many power outages. We imported a propane refrigerator for emergencies from Brazil a few years ago. They don't make them here anymore.
