REC: Roast Beef Tenderloin with Port Sauce
This was Christmas dinner at dear SIL. Funny story about the beef. She bought it at Costco the day before Christmas Eve along with a load of other stuff for the holiday. It was cold out and snow on the ground. She got to the parking lot to load the car when her phone rang, she put the beef tenderloin on the roof, chatted on the phone and loaded the car. Still on the phone she drove home. Upon arrival she remembered the beef on the roof!!!!! A $65 piece of meat gone........ Two others arrived home at the same time and offered to go look for it, they found it three blocks away on the side of the road, in fine shape, perhaps a little extra tenderized! It was delicious for Christmas dinner.
The beef was of course good, how could a tenderloin not be good. But the port sauce was a perfect accompaniment and devoured by all.
