in these hard times im more dedicated to putting up a lot of canned beans, chili, soup ect. I got looking on line and found that some can hamburger. So yesterday I canned 20lbs. What you do is brown it (I added onion) , mostly to get rid of most of the fat. You dont want to overcook it first. Drain it off then put it in jars. A small jar will hold almost a lb and a large jar 2lbs. Don't pack it. what I did to fill the jars was put a folded towel on the counter and kind of hit the bottom of the jar on it to pack in more meat. Then you add a teespoon of salt or two for a large jar and fill about 3/4s full with beef bullion. Pressure cook them one hour for pints 75 minutes for quarts. Even if it wasn't such hard times it makes sense. You can spend a couple hours prepping this burger and when you want to make tacos, chili, sloppy joes, spaghettis ect all you do is grab a jar and dump it in. it will never freezer burn and will last for years and it frees up space in your freezer for other things.
