I just finished a jar of homemade venison mincemeat last night. Yes, it goes really well warmed up and put on vanilla ice cream. My point was that it was canned by my wife 5 years ago. It tasted every bit as good as the day she ran it through the pressure cooker, sealing it in those pint jars.
We keep a large garden and put a lot of produce in jars and also in the freezer. We can enough of one item at one time such that we don't have to do it again for several years. That makes it a lot easier, in my opinion, than trying to process everything every growing season.
