Garlic Butter Steak:
Heat an outsized forged iron pan over high heat and sprinkle steak with salt and pepper. When the pan is hot, brush the steak lightly with oil.
Place steak in the pan and cook for about 3-4 minutes on all sides, until cooked to desire doneness (should be about 135 degrees for medium-rare and 140 degrees for medium).
While steak is cooking, mix butter and garlic together in a small bowl.
Top steak with spread and let it rest for about 5 minutes before slicing (be bound to slice against the grain).
