Coat the beef in butter

• Pat the steak dry with paper towels.
• Rub the softened butter all over the steak in a thick, even layer.
• Season generously with salt and cracked black pepper.

Age the buttered beef

• Place the butter-coated steak on a rack over a tray.
• Refrigerate uncovered so the butter sets and the beef ages.

Sear on the grill

• Bring the steak back to room temperature.
• Grill over high heat, turning once, until deeply browned on both sides.
• Baste with the melting butter as it cooks.

Rest and serve

• Transfer to a board and let rest so the juices settle.
• Slice against the grain and spoon over the pan butter.
