I know you can buy the stuff in jars, but the main reason to make it at home is that your own is so much fresher tasting—and, of course, free of any unwanted additions, such as sugar or preservatives. Also, it is cheaper to make it at home. 🙂
It is very easy:
1 cup roasted shelled peanuts
1-2 teaspoons oil (any oil will do but if possible use peanut, coconut or sesame)
1/4 teaspoon salt (omit salt if salted peanuts are used)
Place ingredients in blender. With the lid secured, blend until mixture becomes paste-like or spreadable (3 to 4 minutes). If necessary, stop the machine and use a rubber spatula to scrape mixture from the sides of the container back into contact with the blade. Continue blending until desired consistency is reached.
For crunchy peanut butter, stir in 1/4 cup chopped roasted peanuts after the blending is completed.
Yields 1/2 cup creamy or 3/4 cup crunchy peanut butter.
Store in a tightly closed container in the refrigerator. Oil may rise to the top. If this occurs, stir before using.
