Sorry to start a new thread on same topic but I need quick help. Getting ready to do my first prime rib. I have a 3 bone 6 1/2 pounder. My plan is to season it, sear it off in the oven at 500 for around 10 minutes, put it in the amerique at 250 with rosemary and garlic and 1 oz of cherry. Bring it up to temp. and then hold at 140 for 4 hours. my questions are in previous thread suggestion was to bring it to 115 - 118 internal. If I am trying to end up at 140 internal for medium rare, will I really get there holdong in the oven at 140 for 4 hours. Also, does the rest of the plan sound right ? Have company coming for dinner and I really want to get it right.
