Much of that stuff is sealed and is somewhat shelf safe for a while. Once the seal is broken though, good practice is to refrigerate it so as to retard the spoilage process.Originally posted by ExtraSlow
My wife informs me that anything you buy unrefrigerated can be kept unrefrigerated after opening. Even salad dressings, mayonnaise etc. That being said, we have lots of room in the fridge, so we do refrigerate that stuff.
but peanut butter? No. Always in the pantry.
