Take that back I have canned Jam's but that is different.
My mother used to can some stuff, but I was always afraid of food poisoning too. I just freeze or dehydrate. Sorry to hear what happened to your grandma.
How awful, and so young too.
I don’t worry about anything pressure-canned, it’s heated long enough and to high enough temperatures, to 240 degrees, to kill all the spores, bacteria, etc. Water-bath canning is low temp so if the food isn’t acidic enough, they will survive. I pressure can everything, even things normally done in a water bath. Mainly because the scanner half full of water is too heavy for me! But there are health benefits too ;)
