Much like topping a finished steak with a traditional compound butter, this perfectly grilled steak gets finished with a fresh herb butter without the bother of making and chilling the butter in advance of serving. This technique of smearing the seasoned butter on the cutting board allows the hot steak to become coated in the herb butter as it rests before carving. This steak is also known as a Porterhouse Grilling Steak and it has the same type of bone you find in a T-bone Steak.
