Warm should be ok. The can does NOT say to refrigerate after opening. I just do it as a “to be sure” kinda thing.
I will test it and see how it cooks up, assuming it looks ok.
It is sealed.
My stove has died and I am looking at crockpot and breadmachine as a way of life, as moving in another is impossible and I don’t want to mess with it and can’t do much anyway.
