I'm so glad I made the trip to get the Prime, Prime rib roast from How's market (Thanks to nudging from fellow Chowhounds.). My goodness was it good! (200d for 3.5 hrs--perfectly cooked).
Last year I used a Costco roast, which in comparison was "chewy". This one melted in your mouth. I hope they run that special ($5.99/lb) again next year!
Because I was making a lot of Yorkshire pudding, I asked for extra fat. When I tasted the Yorkshire pudding I nearly cried. It was BY FAR the best "food" I have eaten in at least 5 years, no kidding.
