Hey everyone! Just got a Master Forge vetical gas smoker for christmas and need a little help with some smoking basics. I'm smoking a 3.5lb pork loin that i've applied a rub to last night. First of all, how lond is that going to take? Also, I've seen some people put a pan of water in the smoker, Is that what most do? Should I apply BBQ sauce before, during, or after the smoke? Not at all? Thanks on advance.
