Thanks to Sarajevo for posting a link for the Foxfire books. They’re great for old time how to and lore. If nothing drastic happens, they’re fun to read. There are about a dozen volumes.
Another good book/s is/are the Tightwad Gazette by Amy Dacyczyn. Hers are directed more to frugal living but has basic recipes like Rika’s above posted soup base. FYI, the yogurt recipe, though not for hit the fan days, is foolproof.
Thank you for the reference.
