1 Big roast or 2 smaller ones?

Hi everyone - first post here, but I've been lurking for a while. My question is: I just picked up a monster rib roast at Costco (13 lbs), and now I'm thinking what a dumb idea! Why not do two smaller ones? Should I just go with the one I've got, or would you, the cognoscenti, recommend that I cut it in two? I was going to salt it and let it sit in the fridge till tomorrow. Dinner is at 4. If I stay with the big guy, how long per pound do you think it should cook? I was going to do it low and slow.

Thanks for your help!

  1. The size of your dinner should depend on the size of your dinner table. How many are you going to serve?

      14, and I'm hoping for leftovers but it's ok if my family loves it and eats it up. Scalloped potatoes, green beans almondine, glazed carrots.

        Cook it whole. Just was at dinner last night for 10 adults 3 children with 11 pounder - two slices left.

        There was a big post on low and slow in the last couple of days - not how I do it.

    2. I've been reading 15 min or so per pound. Would that apply to my big roast? I will have a thermometer in it, I just want to make sure I get it in the oven on time so it can rest. ~ 3 hrs 15 min for medium rare doesn't sound enough...
