I'd love a rule of thumb for the length of time it's safe to save the remains of opened cans of foodstuff. Right now I have a 1/2 can of condensed milk and 1/2 can of chipotle en adobo in the fridge just daring me to use them before salmonella sets in! I'm not a whimp about leftovers and don't adhere to the 2 day rule that some espouse but I'd hate to poison a loved one with tainted chili or caramel. What's your limit??
