I love prime rib and I've tried several methods of cooking it. This Christmas I experimented with the sous vide method and there was not a disappointed person at dinner. Cooking meat using the sous vide way is excellent, and you will not be disappointed. But plan ahead, because this takes at least 24 hours. The seasoning measurements are approximate! You basically want to coat the roast with the dry seasonings. I didn't measure how much I used. As far as the sear, you can do it in the broiler, on the stove or on the grill. I explain the method I used, and it turned out amazingly well!
