I have heard about peanut butter burgers for quite a spell, but I never had the nerve to try one. I recently made some burgers and figured I would give it a try. I thought it would be mediocre at best, but man was I wrong! I was quite surprised at how well it complemented the burger. I am entertaining some people in the near future and I plan on smoking a 10# brisket and I am thinking about spreading peanut butter on the outside and seasoning it (not sure what I am wanting to season it with yet). Does anybody have experience doing something like this? I think it could be really good and help make a nice bark. Any comments are appreciated! I am planning on doing a chuck roast in the same manner that I plan on seasoning the brisket as a test run.
