I have successfully canned a lot of stuff, and dehydrated lots of stuff too. Especially when we have too much produce to eat in the summer.
One winter, we grew our own wheat. Harvested it in June. Hand thrashed it and ground it up in a coffee grinder to make whole wheat bread.
Each year we have attained several new prepper skills. I am feeling more confident now that we will be able to be almost totally self sufficient as it pertains to food, as long as we can remain at home. A rural area populated by social conservatives.
I lost a lot in the crash of 2008, and have gone months at a time without going to the grocery store. Part of that was having preps, and a lot of that was poverty cooking.
