It's something I should do here but don't. I make bone an bits stew occasional. I don't have canning equipment here. How long does it last in a sealed jar?
If it is pressure canned, months if not years. But that is not you. It would have to be pressure canned, water bath canning would not do.
On the counter I would not trust it for more than few hours. In the fridge, maybe a week.
