@DanielsASJ about 3 lbs of shelled pistachios nuts, another two pounds of shelled peanuts. A cup of peanut oil and a very strong blender. And I do mean a stong one because it will over heat!
You don't want to put too much peanut oil because it will become runny. And runny peanut butter becomes rancid easily. It's mostly the oil that goes bad.
Some yes and some no. I usually buy the aldi one or Santa Cruz (I think their ingredients are peanuts and sea salt) and I don’t refrigerate either, though I do go through it quickly. Right now I have crazy Richard’s (100% peanuts) in the fridge and pb2 pure (100% peanut powder) in the cabinet.
Nope. Peanut butter is blended with oil...sometimes with peanut oil, but the cheaper varieties may contain other oils. It's important for peanut butter to stay smooth and spread evenly over bread without clumping, therefore it should not be refrigerated.
Not the stuff from the supermarket. I eat so much of it a jar doesn't last a week. If i get the organic kind from Whole Foods then I have to refrigerate it.
My mother did, and when I was nine I got up early to make my Dad's lunch, the cold hard pb kept ripping the bread, so I would throw it away, by the time I threw out most of the loaf I was bawling my eyes out, so my Dad called off work, called me outbof school, we went to breakfast, went to the zoo and the science and industry museum, then to Star Wars, it was still playing at our local in 1979, the owner bought a copy and kept it playing. When we got home my mother was screeching like a harpy, "Why is the peanut butter out and a loaf of bread worth in the garbage!!!!!!" To which my Dad said, "It stays in the cupboard from now on." and left it at that.
Only peanut butter which lacks preservatives requires refrigeration after opening, otherwise the oils will separate and will go rancid if left at room temperature.
@swirlie even natural peanut butter will be fine without refrigeration. You don't refrigerate you're vegetable oil do you? Same thing. Besides it separates no matter what you do if t doesn't have emulsifiers
