Bistecca alla Fiorentina (Tuscan Porterhouse)

Step 1
Press chopped rosemary onto both sides of porterhouse steak; set onto a plate and allow to marinate at room temperature for 1 hour.

Step 2
Start an outdoor grill using hardwood charcoal, such as hickory. When coals are white and glowing, arrange for high heat.

Step 3
Gently brush or rub olive oil onto steak, then season to taste with sea salt and pepper.

Step 4
Place steak onto grill, and cook until a dark, golden brown (not burnt) crust forms, 5 to 10 minutes depending on thickness of meat. Turn over, and continue cooking until golden on the other side, 5 to 10 minutes more. When finished, place steak onto a platter, and allow to rest for 10 minutes.

Step 5
To serve, remove the two pieces of meat from the bone, and replace the bone onto the serving platter. Trim any unwanted fat from the round (tenderloin) steak, slice into 6 equal pieces at an angle to the grain, and fan out on one side of the bone. Slice the rectangular (loin) steak into 1/4-inch slices at an angle to the grain. Fan out on the other side of the bone. Finish by garnishing the platter with lemon wedges and a sprinkle of additional sea salt.
