Let the steak rest at room temperature. Meanwhile prepare the Lemon – Orange Horseradish butter by finely chopping the parsley and garlic together. In a small bowl mix together the Horseradish, butter, lemon juice, parsley and garlic. Season with salt and pepper. Mix well and place in the freezer for 5 minutes.
In a large skillet, use two skillets if the steak is too close to each other in the pan, place a large amount of fine salt. Heat the pan on high. When the pan is nicely hot, add the steaks and sear each side for a couple of minute per side. Lower the heat and cook another 3 minutes per side.
Place the steaks on a plate and serve a dollop of the lemon orange horseradish butter in top of the steak.
