Hamburger rocks? Ya, I said that, too. But somehow I stumbled onto a survivalist (the sky is going to fall one day) type site. While I do believe in being prepared and having knowledge to be self reliant, I'm not an extremist in that area...my extremist views lie in the 'let's all do our part to protect the earth' category. :o)
Okay, back to the hamburger rocks. This is the link to the actual page on how to do it:
It's basically frying your ground beef, rinsing all the fat from it, and dehydrating it. From there, the author states that you can pack it in sterile jars, seal and keep it for two years or more! This might be the ticket for you if you get a whale of a deal on hamburger, but don't have freezer space for it.
I have to admit that I have been feeling a little guilty about plunking everything into the freezer because it's faster, easier and not so dang hot. Canning in the kitchen on a hot July day in Kansas is not a treat, even with air conditioning that's running non stop. And I'd rather not be so green here and forego the a/c. However, I did read about someone who did a boatload of water bath canning at one time with a small metal stock tank over hot coals or fire outside. I don't know if that would fly here at our house, but I'm sure willing to try it on a smaller scale..like the grill. But I digress, the point here is that I have all the canning supplies and it would be the greener thing to do if I wasn't running a freezer 9 months a year.
A couple of great sites for canning and preserving are http://creativecanning.blogspot.com/ (put bacon in the search bar and see how she's canned bacon!) and http://www.pickyourown.org/allaboutcanning.htm
