Kamenoko, also known as "亀の甲" in Japanese, is a part of the "Shintama" (新玉) section of the cow. Located near the base of the hind leg, the Kamenoko surrounds the femur and is characterized by its well-developed muscle fibers due to the high amount of exercise this area undergoes. This cut is lean, with minimal fat and a rich, red color. The name "Kamenoko" is derived from its shape, which resembles a turtle's shell. Kamenoko is versatile in cooking and is often used in stews, roasts, and steaks. It excels in slow-cooked dishes like beef stew, pot-au-feu, and curry, where the meat becomes tender and flavorful over time. It can also be thinly sliced for grilling or used in yakiniku. Due to its lean nature and high protein content, it is a healthy choice for those seeking nutritious meals. Properly cooked, this cut offers a unique texture and flavor, beloved by culinary enthusiasts.
