Find a shop (usually a health food shop) that has a peanut grinder. "Real" peanut butter is just ground peanuts. Nothing else.
The shit you buy in the supermarket has icing sugar added to it to sweeten it up. A guy at my gym is a food chemist, or whatever you call them. He said that not only do they add the sweetener but they also hydro the fats so that you don't get that 'yukky' oil floating on top.
One place I went to not only had a peanut grinder but also one with almonds in it. I shit you not, you would think you died and went to heaven with 14 virgins (preferably of the opposite sex).
Melrose have some nice ground nut products. Pricey but very yummy. Try the 3 nut mix. More addictive than crack.
