I am going to be Smoking 16 lbs Pork Shoulder Butt for Saturday evening, plan on serving it around 6:00pm. I have smoked on in the past but it was only about 8 lbs, this one is double the size. The one I smoked in the past took about 9 hours and turned out perfect! They only had 2 of them at Sam's the day I went and both were about the same size. My understanding is that it is about 1.5 hours per pound at around 225-250 temp? So that would take about 24 hours to smoke, so starting at about 5:00pm with the fire if I want to get it done by 6:00pm on Saturday? I am not going to use any rub this time because my Mom and brother hate rub. I have tried all sorts of different kinds and even the one I bought from this website, but they still don't like any rub on any of their meat. They say they like to taste the Meat and with the rub they can't taste the meat. But they love BBQ Sauce on their meat. Yes I know they are weird unfortunately they are my family! So I am going to use some homemade BBQ sauce of mine. So about while I am smoking it, when would be the best time to start to Sauce it up? Also if I remember right their is a point in time that you wrap it up in Aluminum Foil and put it back in the smoker. So about what time do you do this or am I wrong on this one? I will be using Hickory Logs and Hickory Chunks to smoke this. Thanks for all your help and suggestions. I will make sure I take pics after I get done this time, because I forgot to take them the last time I smoked my brisket!
