DIY peanut butter and decided to give it a try. It really was as easy as they described: dump peanuts into a food processor and run it for five minutes or so. I probably could have processed it a bit longer - it wasn't super creamy smooth. That works out fine, though, since I like my peanut butter with texture.
My food processor is one of those little hand-held things, so I'll be sticking with small batches. But that's probably a good thing. I will have to start experimenting with flavors or maybe different nuts. Hmmm.... cashew butter or almond butter may be next on my list.
