I'm Cameron from glenpool Oklahoma. I just got back from the butchers. Picked up 2 pigs my kids show'd for 4H. A couple weeks ago I picked up a little master built electric smoker so I'm trying it out as we speak. 2 racks of ribs, 1 tenderloin, and one 3lb pork butt. This is my second time using the smoker and never smoked a butt. How long at 225?
