Dear DUmmies:
Even thin rib roast is best cooked in the same manner as thicker ones--fat side up, bone side down, salt and pepper only, baste in juices every 30 minutes or so, 325 degrees, 20 minutes per pound, don't go any more than medium rare (140 degrees internal), let it rest for 10-15 minutes under loose foil before cooking.
Jesus, do I have to do EVERYTHING for you ****ing worthless ****tards? Oh, and DUmmies, make sure you stick your heads in the over for an hour or five to make sure the roast is done first.
