Peanut Butter
Unlike the jelly or jams that go so well with it, peanut butter should be kept at room temperature. It will likely get dry and hard if stored inside the fridge. For creamy, spreadable peanut butter it’s advised to keep it in a dark, dry place. The exception is all-natural peanut butter which can separate if not refrigerated.
Honey
According to the science section of Business Insider, storing honey in the refrigerator can cause it to crystallize. It will also get extremely thick and difficult to pour or spoon out. Honey is a food that has the ability to naturally preserve itself and can stay good at room temperature for an indefinite amount of time.
