Do you feel that canning is a necessary skill?
So background is, no one ever taught me to can. And while I'm all about learning new skills on my own (which is what I've done for most I have), canning scares the heck out of me.
I usually just freeze or lacto ferment items items that I want to preserve. But in getting pushback from some local acquaintances that without knowing how to properly can I'm not prepared enough should a SHTF issue arise.
