I don’t know how I missed posting this one. This was a dinner I prepared for six people, sous vide, the night before leaving town for the holidays. Sous vide makes cooking for a dinner party so much easier. I did the standard 134 degrees for about 1 1/2 hours, I think, as these were pretty thick. Sure nice to have every single filet come out perfectly medium rare. Then it was into a hot cast iron skillet with ghee to sear on both sides. As always, click for the high quality image.
The other great thing is that I can take extra care for the sauce. Essentially, it’s my bone stock reduced only enough to get rid of the watery flavor. Then for six servings, I added about 1 cube of butter, 6 teaspoons of crumbled blue cheese, and about 2/3 of a tub of crème fraîche to desired sauciness. You might want to do the cheese a bit at a time to make sure you don’t overdo it. Don’t salt until done, if at all, and especially if you choose to use roquefort cheese.
The mash was two large celery root bulbs and a single russet potato. Those, you boil in whole milk, strain, then blend in the food processor with butter and cream until you get the consistency you want. Celery root is so fibrous that there’s no way other than a food processor to get it right, so learn from my previous #FAIL.
This is sort of my own version of a French classic: tournedos au roquefort.
