This Instructable will cover my technique for pulled pork. The methods are similar for brisket and ribs as well.
The smoker that I'm using in this Instructable is a Traeger pellet grill, but the cooking and preparation are the same regardless of smoker type. I also smoke with charcoal with Weber Smokey Mountain, and a Weber kettle grill with a Smokenator attachment.
Just remember - low and slow. Low temperature cooking for a long period of time!
