Then remove any external tendons from the meat and trim a little. Cut the piece of meat lengthways into 2 thick 500g slices. Salt the meat roughly on both sides beforehand. Heat the clarified butter in a pan. Put both slices of meat in the pan and sear them briefly and hot on both sides until they are nicely browned. Put the meat in the preheated oven and wait with a thermometer until a core temperature of approx. 50-52 degrees has been reached. Fry briefly in the pan until a core temperature of 54 degrees (medium rare or slightly pink) or 56 degrees (well done or well done) is reached. Cut into plate-sized pieces and serve.
