1. Is cold peanut butter a misery? I grew up in a cupboard pb home, and I enjoy fridge pb as much as cupboard pb. What temperature do you keep your fridge at?
2. Storing upside down is a precaution against oily messes because the oils separate on top of the peanut solids, and so is under the peanut solids when upside down. Also, I mentioned that at the fridge temperatures the oil congeals, and so remains mixed when refrigerated, avoiding any oily mess.
I discovered that it's much easier to dip apples slices in peanut butter if I nuke the peanut butter for 30 seconds. Now I don't get frustrated by my apples breaking off in my peanut butter.
