Picked up a 7.9 lb. Boston butt yesterday. Rubbed down with mustard and Bad Byron's Butt Rub. Figured I would play it safe for my first long smoke. Got the LBGE up to 225 and put her in at about 11 PM. I then proceeded to check my new Maverick ET-732 every five minutes. Reached 200 at about 3:30 PM today - 16 1/2 hours later. Wrapped in foil and a few towels and placed in a cooler until it was time to eat. Turned out great! Plenty of leftovers!
Question: When you do a long smoke and get your temperature stabilized, do you have to continually adjust it every hour or so? I had to constantly adjust my vents - the temperature would get above 250 so I would close it down JUST SLIGHTLY and it would stabilize around 225 and then about an hour later, it would dip to the low 200s. This seemed to be a cycle. Is this just part of doing a low and slow or was I doing something wrong?
