I did three racks of BRITU ribs for the first time on Monday, and they came out excellent. My wife and I agreed that they aren't the best we've ever had, but it definitely came out much better than anything I had ever attempted pre-WSM.
I only had two slight deviations. I ended up using wood chips and not chunks. I wrapped them in foil, and I think I had about the same amount. Also, I could only get the Jack Daniels chips for white oak. Neither deviation probably affected it all too much, but... great recipe. I will do again -- after I try out the competition rib recipe in this thread.
