On GFW's website, I found directions on cooking a 4.9 lb. bone in prime rib. It suggested cooking at 370 to 400 degrees and removing when the meat was at an internal temp of 135 degrees and letting it rest for 15 minutes. However, what would be the approximate amount of cooking time? I need to know that in order to prepare other food to coincide with the beef, when ready. I would have written to (I think it's Gordon) but there wasn't any e-mail address. Thanks.
