Remove the roast from the bag reserving the cooking juices for an au jus.

Notes
1. Avoid black pepper and fresh garlic as they don't do well over a long cook.2. Check water level from time to time and top it off it necessary.3. Searing the meat for added flavor prior to slicing is an option. Pat the meat dry with paper towels. Sear on all sides in a lightly greased hot cast iron skillet.4. Cooking sous vide at low temperatures does not melt away fat, so some extra trimming post cook may be needed if you have a well marbled cut of meat.
