Tomorrow I'm going to be using my new grill that has a side fire box for smoking. I have a chicken brining right now and I've also set out a pork roast that I've rubbed w/ a dry rub. I bought some hickory chunks also. Was just wanting some advice as to how long to smoke either meat for. The chicken I'm doing beer can style as well. Should I wrap the roast in foil? Does that take away from the smoke flavor or hinder its ability to cook?
