Preheat your grill to high. Prepare the steak by scoring the layer of fat on top. Do this into in one-inch squares.
Rub kosher or coarse salt into the fat layer of the beef, ensuring you get it into the crevasses created by you scoring the fat. Season with freshly ground pepper.
Sear the steak won the grill with its fat side down. Grill for 3-4 minutes.
Remove the steak from the heat and place back on a chopping board.
Slice into medium-thick strips and apply a sprinkle of more salt on each strip.
Put each steak strips back on the grill and cook for 20-25 minutes, turning every 5 minutes.
Use a meat thermometer to monitor internal temperature. When the internal temperature reaches 130°F remove the steaks from the grill.
Leave to cool for 5 minutes. Serve up and enjoy.
