If my memory is good, a prime rib roast is a roast made with the same part used for the ribsteak, except not sliced in 1'' slices? Am I right on that ?
If so, how do you deal with the bones ?? remove them then tie it back with roast rope ? or deal with it once cooked ??
Interesting I was planning that for Friday night supper and was asking myself alomost the same questions!!
