Essentially two steaks in one, impressive t-bone steaks include both a large portion of strip steak and a much smaller portion of tenderloin separated by a t-shaped bone. A meat lover's favorite, they're extremely large, with each steak weighing approximately a pound.
This wagyu beef (aka Australian kobe beef, kobe-style beef) is from an Australian breed of cattle descended from Japanese herds and specially raised to increase its percentage of fat marbling to consistently high levels. More marbling leads to more flavor, tenderness, and moisture as the fat melts during the cooking process. Thus, wagyu t-bone steaks are both more flavorful and more tender than those cut from conventional beef.
