I have a neighbor who wants a prime rib for Saturday but I'll be out of town. Has anyone ever cooked a prime rib ahead of time? The only thing I can think of is to try to cook it extra rare and then slice and reheat in broth. This scares me because I have a hard time pulling the meat for rare. I always seem to over cook it a bit. I would like to help her out but I certainly don't want to ruin her dinner!
