Peanut butter is made from peanut-free peanuts, cooked and ground to a fine paste. Peanut butter is a rich source of energy, vitamins (B3 and E), minerals (magnesium, calcium, iron, phosphorus, zinc and copper). Because of its high oil content, the peanut talc is likely to settle down after some time in a vessel. This is a natural reaction and should not bother you. Just mix the paste until a homogeneous consistency is achieved.
