Peanut Butter is a thick spread made from ground, dry roasted peanuts. Some products add additional oils, such as Palm Oil and other ingredients such as salt and sugar to alter the taste and texture. I prefer the kind that roasts the peanuts with their skins on, with no additional ingredients. Any oil that you see inside the top of the jar is usually the natural oil from the peanuts. All you need do is give it a good mix before use.
