we expect maybe 15 for Christmas Day so I can’t really do a prime rib, but I might get a good plain old rib roast....seasoned and roasted the right way, it can be very very good..
We have about that many, as well. My nephew and his wife host the family holiday dinners and they get a ham and I bring a whole beef tenderloin. I try to get it on sale already peeled and lucked out last year with one for around $10 pound. It was about 8 or 9 lbs. I dry-brined it the day before and then roasted it quick. We served it room temp, sliced thin with a great Rochefort/garlic sauce. Along with many other side dishes, it was plenty for everyone. So tender and flavorful. It’s my Christmas “present” to my family. Just an idea.
