... I suppose I should try to learn how to bake bread before the SHTF, but I haven't done that so far.
I make bread all the time. Had a bread machine for years (my MIL gave me as a gift) until it broke. I didn't replace it until a couple of years ago when I saw one at our church rummage sale new for $10. A few months later it fell of the counter while kneading. Oh, well. I didn't really need it. Most of the bread I've made has been by hand. Don't get stuck on kneading--for a lot of breads it's not that critical. I make pizza dough, rolls, french bread, whatever and I'm not interested in standing around and kneading. It's all gets eaten pretty quick so I suppose it's good. If I'm making a special recipe from some cookbook I will follow the kneading instructions but for everyday I don't worry about it.
I have been putting off the extra step of grinding my own flour though I hear it's really something in freshly baked bread. I've found adding freshly baked bread to a meal can make a so-so meal seem better. It's fun to experiment and try recipes from around the world.
