USDA Complete Guide to Home Canning
USDA National Institute of Food and Agriculture (with UGA/NCHFP)
THE authoritative, safety-tested home canning reference (pressure vs water-bath, altitude adjustments, hundreds of tested recipes for fruits, tomatoes, vegetables, meats, pickles, jams). Exactly the offline reference preppers want, and as a numbered USDA bulletin it is public domain.
Editor's notes
Public-domain status attaches to the USDA bulletin itself, NOT to the surrounding NCHFP website (all rights reserved) or to healthycanning.com's commentary — bundle only the USDA PDFs. Amazon hard copies are known to be corrupted/incomplete; use the official PDFs. Do not alter processing times/temps in any way — this is safety-critical content.
