I'm probably the ONLY person that doesn't know this....but....
I never got the oil completely stirred in so the peanut butter at the bottom would be REALLY dry and hard. SO..I searched the web and found two similar things: store the peanut butter jar upside down in the cupboard until opened OR store the peanut butter jar upside down in the fridge and turn it daily until opened. I'm not sure if the results are different from the two methods - so, I have two jars of unopened peanut butter, one just sitting upside down and the other in the fridge that I'm turning daily. I'll post if one method is better or if there is any difference between the two.
Well, I opened the jar that was just sitting on the counter upside down and I was thrilled with the result. My peanut butter was already "stirred" and the oil was mixed throughout !!! YEAH !!!!! An easy way to "stir" my peanut butter !!!
I opened the jar that had been in the fridge that I was turning upside side every day. I have to say - I think I like this better. It seems to be better mixed.
