I tried going the natural peanut butter route before, but I couldn't handle the oil that would settle in on top. Then I discovered this great "invention" at Whole Foods...a peanut butter grinder! It's basically a giant machine filled with peanuts and you can make your own natural peanut butter at the touch of a button. I usually get enough to last me about a week. This way, the oil doesn't have enough time to settle, it prevents me from eating too much because I don't have a whole jar, and, frankly, I think it tastes SO much better.
Of course, I occassionally give in to pressure and also buy the Dark Chocolate Peanut Butter, but, hey, no one's perfect!
