i tested out that recipe stevenduang posted, but I had to make some adjustments as my girlfriend prefers medium / well-done
so I bought a 6lb prime rib and was suppose to keep it at 500F for 30mins (according the the recipe) but I left it for an hour instead and it was medium not well-done yet as there was a bit of pink but it was SO damn good
heres some pics of it buttered up

served with some gravy + mashpotato... damn it was a good meal
3 bone for 6 people, nothing was left and everyone was stuffed
the result?
probably the best prime rib I've had yet, same goes for my girlfriend and her family, everyone loved it !
