Put the peanuts in a food processor with a sharp blade and process until as smooth as you like it.

If you are adding oil, drizzle it into the food processor while its running. Add as much as you need for the texture you want - but be careful - you can get too much really fast!

It is pretty runny at first. Once it's refrigerated it thickens into a paste. I also used roasted, salted peanuts. You can leave the salt out if you want. Store it in the refrigerator for one to two weeks.
