I am having a reception for the christening of my twins Sunday. Mrs. O Face wants roast beef. The thing I am trying to figure out is the best way to cook it. We have to leave for church around 10:15 and won't be home until about 12:30. I clearly don't want to roast it when we get home because it won't be ready for a an hour or more. So the choices are (1) try slow roasting it -- sear the thing and then roast it at 225 for like 2- 2 1/2 hours; or (2) roast it at a higher temperature for an hour or so before we leave for church and then just have it cold. The gravy will be warm. What do y'all think?
