When we lived on a farm, Mother canned a lot of vegetables and preserved fruits. We also had a smokehouse which was one of the most pleasant smelling places one could imagine.
After around 1955 we had a freezer which made everything much easier but if you are worried about electricity then canning, etc. would be the way to go.
I know a lot of people dry some kinds of produce but we didn’t do much of that.
I have found to my delight how very convenient it is to grab a jar of ground beef out of the cupboard for use in my dinner.
I use as much from the jar as I need, then refrigerate the rest for later.
