Preheat your oven to 140°F.
Heat up a heavy stockpot until it is almost smoking. Add a generous amount of oil, about 2 tablespoons, and allow the oil to get hot and almost smoking. Season the beef generously with salt on top and bottom and then deeply brown the beef on all sides (including the edges).
Transfer to a roasting pan and roast until the deepest part of the meat reaches 130°F (or your desired doneness) – about 3 hours. Remove and let rest for at least an hour or until ready to serve.
Slice off the bone and cut into triangular pyramids. Serve with salt and pepper and sides.
