Great post! Over the years, I’ve learned how to can and use a pressure canner and food dehydrator. It’s absolutely critical to stay up to date with canning techniques. I don’t know how much bad advice I’ve read over the years, canning butter and water bathing green beans for example, but I have to say that if I was having issues with arthritis then the first thing to go would be the canner. Once that sucker is filled with water it’s quite heavy! The dehydrator would definitely be a keeper and you’ll have to tell us how the freeze dryer works out.
