Hello to all. I am originally from Arkansas, and have lived in TX, FL, and now Virginia. I am new to the smoking world, and own a 40" MES. I love everything about smoked foods...there is really nothing better. I want to be successful at everything I do, and smoking foods is definitely one area I want to succeed. I do have several questions, they may have been answered on previous threads, but I have not ran across them so far. Is there an iPhone app or website to help me determine the proper temps and cooking times for various cuts of meat? How often do I replace my wood chips in my 40" MES? I am currently smoking a 8 lb Boston Butt, and I have the smoker set at 235 degrees for 10-12 hours. I am using applewood chips (soaked 30 min prior to use), but I do not want to add too much if it is not needed. Should I invest in pellets instead?
