KD, Start with the
ball blue book and then get into recipes from folks like
Pick your own and university extension services. Don't let the germafobes dissuade you. I can fruits, jellies and jams, meat, stock, seafood and much more. The key to safe food processing is learning and understanding what things live and/or thrive in different environments. Many things cannot thrive in an oxygen free environment—while some thrive in an oxygen free environment, and others can't survive high acid content. Salt and sugar keep different bugs out. Super high Temperature kills others.
It might surprise you to learn that the fancy sauces developed in France were largely developed to cover the taste of rancid meat (no refrigeration then), people didn't die from food poisoning because they cooked it hot and long.
The easiest way to get into it is start with proven safe recipes and learn as you go. A good pressure canner can double as a water bath canner. Avoid dry air canning unless you're trying to protect things like dry goods. It is easy, rewarding and can save you lots of money... When I lived in VA I belonged to a CSA and during canning season would buy "canning" vegetables (things too ugly to sell on the stand) really cheap and can them. We also eat a lot of beans, Next time you're at the store look at what a can of prepared beans cost, then look at the price for a pound... You can make 7 cans of beans out of a pound (btw, I go my beans for 19 cents a pound). So happy canning....
