A T-bone steak is the combination of two of the best cuts of beef, the NY Strip and Filet Mignon. This cut The combines the meaty flavor of the New York strip with the signature tenderness of the filet mignon. The T-bone makes a good candidate for your backyard grill. Take care, though: The leaner tenderloin cooks more quickly than the strip side of this dual cut, so you need to keep it farther from the flame to achieve your desired doneness for the meat on both sides of the bone.
