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!
Step 1: Start with the meat
When you buy a pork shoulder, they are available as boneless or bone-in. I use either, depending on what's available. Some prefer the bone-in, and say that the meat is more flavorful. I have not been able to tell the difference.
I usually buy meat at Costco. They have great pork shoulders, ribs, and brisket.
Most of the shoulders are between 14 - 18 pounds.
