I recently tried to smoke a boneless pork butt around 4 lbs I rubbed it down with yellow mustard and a local seasoning. Set the temp on my electric smoker @ 200 degrees. It sat in the smoker all day at least 12 hours and never reached 190 IT. Any thoughts? Was my temp too low? I've heard of meat stalling during the cooking processpray, was I not hot enough to overcome this stall?
