Just getting around to posting my last prime rib on the Weber. Sorry the pics are a little hazy, I took them from my phone. Basically, I slathered it with butter to adhere the herbs de provence, smoked with Grove Lump and a little bit of hickory for good measure. 270 degrees (+/- 20 degrees lol) for about 5 hours. I let the roast come up to room temp as I got everything ready, thus the shorter cook time. Bon Appetit!!!
