I learned from my mom. Dad did not hunt, but when chuck roast went on sale mom would buy a shopping cart full and go to work.
This is how I do it, very easy:
Cut good clean meat into 1 inch cubes. Pack warm jars, leaving about an inch of head space. Add 1 tsp salt. Process an hour and a half at 10 lbs of pressure.
I have friends that add peppers, onions, whatever. Have not tried that.
One of my favorite methods, just kind of time consuming. Best done on a cold snowy day with a football game on.
