Season steaks on both sides and allow the steak to come up to room temp for about an hour.
Fill a charcoal chimney with charcoal and light. After about 20 minutes when the flames are coming out the top and the charcoal is fully ashed over dump into the grill.
Place grill grates back on, make sure all vents are open and shut the lid. Allow 5-10 minutes for the grates to heat up before placing the steak on.
Place steak on the grill at an angle and rotate after 60-90 seconds to get cross hatch grill marks.
Flip steak and repeat the process. If necessary, continue to flip steaks until the desired temp is reached.
Once the steak reaches an internal temperature of 130°F (for medium rare), remove from the grill and allow 5 minutes to rest.
While steak is resting, add a pat of butter and tent loosely with foil
Slice steak across the grain and enjoy!
