Heat a well-seasoned large cast iron skillet over high heat until smoking, about 5 minutes.
Season the steaks with kosher salt, black pepper, and ground cumin.
Add the steaks to the hot skillet. Cook until a brown crust forms on the bottom, about 2 minutes.
Flip the steaks and cook them for 2 more minutes on the second side.
Finish by cooking the strips of fat on the edges of the steaks, about 30 seconds for each edge.
Transfer the steaks to plates, loosely cover them with foil, and allow to rest for 5 minutes before serving.

Notes
Consuming undercooked meat may increase your risk of foodborne illness. I always cook lamb and beef steaks, chops and roasts to medium-rare. But you should make your own decision.
