Pre-heat cast iron over high heat. Drizzle olive oil in the pan.
Generously coat your steaks in Maldon salt flakes and fresh cracked peppercorn.
Place down in the frying pan, and sear for 5 minutes. Do not disturb your steak while it is searing.
Flip your steak. Add butter and crushed garlic to the pan. As butter melts and froths, tilt your pan and spoon the butter and garlic over your steak.
Allow to sear for an additional 5 minutes for medium-rare.
Place your steak on a cutting board, and allow it to rest for at least 10 minutes. Slice, and serve.
