I know nothing about this but happened upon this:

“The only thing you can not oven can is dry foods that have oils in them. I oven can almonds, and pecans, but walnuts do not can good at all. They will go bad, but it is due to the amount of oil, so they get tossed in the freezer.”
Thanks! We are going to give this a shot with almonds. Will try them in a couple of years to see what they taste like.
