For some strange reason I had not made peanut butter. I have made jams, pickles, jellies etc and always knew how to make peanut butter but never actually did it!
Peanuts, shamelessly I chose roasted and salted and a small amount of oil, I ran out of sunflower and used peanut oil. Say 4 cups to 1 TBS. Whizz in food processor for a few minutes.
It is very cheap too!
