That rib looks amazing FT.
Did a single fore rib of beef as a giant steak on Saturday (To share). I'm used to indirectly cooking on my weber, and have used this method before for roasting lamb, but straight over the coals seems to be the best method for beef steak.
Rib had been salted and rubbed with garlic about 5 hours prior to cooking, then just seasoned with pepper and sprayed with a light olive oil prior to cooking.
Was delicious, with BBQ'd asparagus, tenderstem broccoli, and oven roasted garlic mushrooms and potato gratin
Roasted some marrow on the BBQ at the same time, but it was overdone and melted away sadly.
