Yesterday I tried canning ground beef for the first time. I think it went well but have a few questions. After 90 minutes of pressure the canner sat for an hour and pressure had released. I removed the lid and let it sit to continue cooling. The jars were bubbling and kept doing that for a couple of hours. Is that normal? Also, there was a fair amount of fat in the water of the canner. (outside the jars) Is this normal also? I am worried that something went wrong and my 12 lbs of beef is no good. The lids are slightly dished in and before bed I put the jars in the refrigerator. They were slightly warmer than room temperature when put in the fridge.
