Flipping the Steak
After 4-5 minutes, flip the steaks using tongs. Cook for another 4-5 minutes for medium-rare, or until desired doneness. For added flavor, place a sprig of fresh rosemary and a tablespoon of butter on each steak while cooking.

Resting the Steak
Once cooked to desired doneness, remove the steaks from the grill and let them rest for 5-10 minutes. This allows the juices to redistribute within the meat.
