When I was younger, our family would can applesauce, all sorts of jams, peaches, beets, and we froze a lot of stuff too. Making applesauce was always fun

Now, I freeze a lot of things, but haven't canned anything yet. There's a big warning in the owner's manual for my gas stove about not canning on it, but no explanation why. Something to do with the pilotless burners maybe?
