Well I smoked my first butt a week ago and while it turned out ok I know at least a few of the mistakes I made. One I cannot figure out is why the bark of the butt imparted a bitter taste. So much so that when I pulled it I tried not to include much of the bark in the finished product that I shared out. I used apple wood and smoked for the first 6 hours. I figure I either used too much smoke or it had something to do with the amount of rub I put on. I definitely used a lot of rub! Any help would be greatly appreciated!
