I cooked my first Boston Butt on the large egg Saturday night and just had a question or two. I put it on and thought I had the temp stabilized, but left for about an hour and it had crept up to about 300. Once I got it back to between 230 and 250, it stayed there till I went to bed (about 11 hours total). When I checked it again about six hours later, it had dropped down below the point of even registering. I pulled it off, stirred the what little coals that were left, and put it on for another hour (total of about 18 hours). I then double-wrapped in HDAF and put in a Playmate cooler, and served about five hours later. It turned out great, but I was wondering if I should have done something different with the fire to keep it going the full time. I had about half new and half old BGE chunks. I'm thinking I may have been lucky this time and need to get this straightened out!! Thanks!!
