I have had my Masterbuilt Electric Smoker for about 6 months but have never tried a Boston Butt. I bought a good looking 7 pound butt at Publix and when I got home washed it with fresh water, applied lots of L&P Worcestershire Sauce, then rubbed it down with a homemade rub. Put it in the fridge over night and in the morning put it in the smoker. I also used an AMNS for extra smoke. Ten hours later the piece of meat was at 180 degrees and ready to be wrapped in foil for an hour. Turned out pretty good for my first BB. Thanks for the info Johnnie.
