I've had 3 smokers in the last 6 months. My first was a Cajun Electric, the second was an Oklahoma Joe (original) MINI and now my Masterbuilt 30.
Between learning to smoke, improving my technique, and my new MES Smoker (oh, and probably just good ole plain patience)...my QUE has improved greatly from the first smoke 6 months ago until now.
This particular 7lb Boston Butt was cooked for 10 hours uncovered, 2 hours covered and 1 hour uncovered again. Basted with its own juices and slathered with just a hint of sauce with some apple jelly mixed in with it on the last step.
It turned out FANTASTIC!!! Here's a pic of it just before I put it into it's resting mode.
