I did something just recently. Canned Venison. We bought a pressure cooker. All we did was cube up some venison and fill some jars. We added a little water and salt. I think most of it was roast meat. Then cooked it in the pressure cooker according to the instructions. Last night we took the jar, I spooned out the few floating fat chunks, then dumped it into a skillet to heat it up, mixed in some brown gravy mix. Then pour over some mashed potatoes. It sure was good.
