The problem with all natural peanut butter is all that tasty peanut oil comes to the top of the container. When I tried to stir the oil back into the peanut butter some of the oil would slosh out of the jar. A friend suggested a good way to combat this was to store the peanut butter container upside down in the pantry when you get it home from the store. When you open it, all the oil is at the bottom and easier to stir in without sloshing. Once it is opened up we stick it in the refrigerator right side up and it pretty much stays combined.
