My canner arrived today. It was heavy and solid...and on the side of the box it said, "Not for use on flat or glass topped stoves."
Funny, Amazon said nothing about that in its product review. Back in the box, back to Amazon. Back to the drawing board.
It turns out, you can't use any pot on a glass-top stove unless the pot has a flat bottom. This rules out most pressure canners (Presto makes one, but I can't find anywhere locally that will test the gauge, and I'm not willing to risk that) and boiling-water bath canners. I am now in search of a large, flat-bottomed, heavy-duty stock pot. I may not be able to pressure can, but at least I'll be able to put by tomatoes and other high-acid things, like chutneys.
Anyone have a lot of great recipes for beets? I bought a few pounds to pressure can...
