A gas grill was used on these steaks. Heat grill to 450 - 475 degrees F. When grill reaches that temp and steaks are room temp, sear steaks on hottest part a grill 3 minutes. Rotate steaks a quarter turn (for the 'X' type grill marks) and grill another 3 minutes. Flip steaks to other side and grill 3 minutes, rotate 1/4 turn and grill another 3 minutes.
