Not sure why you would put even the best gravy in the world on a rib roast aka Prime Rib. I will just hold my tongue.
What IT did you cook it to?
...they served it by pouring canned gravy over it.
I tried to talk them out of it, but to no avail. I grudgingly gave in because I didn't want to be "that guy" who needs to have everything their way in the kitchen. It was my first time working with them and I didn't want it to be my last. The logic behind it was two fold. First we had way too much gravy and needed to get rid of as much as possible. You cannot let anything go to waste! The second argument was that it would keep the meat warmer longer.
The IT was 135* when I pulled them. I would taken them off earlier if it was just for family and friends. However, since it was for a crowd I figured it would be safer to go more mainstream. The beef pictured did have the drippings and some hot beef broth poured over just before the picture was taken, so it does look more done than it was.
I don't know if I mentioned that the meat was wet aged for around 35 days, I think that also added a lot to the flavor. It was one of the best roasts I have done. If I can catch that meat sale again I will stock up!
