New to smoking. I have smoked 2 chickens with Jeff's rub with good result, so I thought I would step it up a notch and go for pulled pork. Purchased a 12.5 lb 2 pack at Costco. I am assuming (perhaps wrongly) that it is butt. The label said boneless pork shoulder, so maybe some picnic too? One of the 2 pack shoulders was noticeably larger than the other. I was hoping they would be roughly the same size. I would estimate one at 7 lbs and one at 5.5 lbs. I will be smoking on a WSM 18". I am also trying a batch of Dutch's baked beans that I will put under the pork for the last 4 hours of the smoke. I rubbed the butts this morning and will post some pics shortly. The original plan was to start the smoke about 4am tomorrow for a 5pm party, but after seeing the size difference I may bump it up to a 3am start. I will be smoking over apple and pecan. Any suggestions or critiques are appreciated!
