I'm making a mole sauce in a large quantity, and I was thinking that instead of freezing it, would this stuff be shelf stable if canned? The one I'm making now has dried peppers, chocolate, spices, lard, onion, tomatoes, plantains, raisins, almonds, and chicken stock. I was thinking of pressure canning it, but I'm not versed enough in the preservation sciences to know if it would keep at room temp.
