Mix sugar and seasonings. Pat steaks dry. Sprinkle (lightly!) mixture on steaks. Heat a cast iron skillet with a teaspoon of vegetable oil until it begins to smoke. Cook steaks on one side for 3 minutes taking care not to crowd them. Turn them over and cook them 3 minutes for rare, 5-7 minutes for medium rare. Remove from fire and let sit for 8 minutes. Plate and serve.
