Will definately do the Introduction, as for the rubs I bought Butt Rub for one which has a bit more spice the other was a little sweeter and was Brown Sugar, Garlic and Onion Porwder, little paprika, cumin, cayenne, and cocoa powder. As for the injection it was a friends recipe that was basically Scott;s Barbacue and Carolina Treet with some coca cola, garlic powder, red pepper flakes, and molases. Both were very good and will definately take your advice and try the Boston Butt next time..any advise will be taken and tried here, my buddy and I are going to try ribs and chicken this week I think...wish me luck.
