A recent post by Freyadog reminded me of this... I have several can seamers that I've scored on Craigslist, including an electric model that does everything from a #1 can up to a #2-1/2 and a hand-cranked #10 sealer. While trying to figure out how to can wet food, I stumbled upon the web site for the University of Alaska's Cooperative Extension Service. These folks have a number of publications (most of them free) that describe how to set up and use can seamers along with instructions for canning various types of food like meat and fresh or smoked fish. Just select the publications you want and they'll mail them to you. Some are available online as PDFs. You don't need to be an Alaska resident and they don't even ask. If you aren't an Alaska resident you might consider ordering your publications by mail and including a small ($5?) check to help support the service but you certainly don't have to. IMO, all preppers should own a can sealer, scads of cans and a pressure canner. How else are you going to preserve that elk or stringer of fish? Jerky is going to get old quickly.
