I used the "tail" of the tenderloin (narrow end) for this recipe. I buy a whole tenderloin about once a year and have the butcher trim it. From that, the butcher grinds the trimmings (produces about 2 to 3 pounds), which we use for burgers, then I cut the trimmed tenderloin into steaks, freeze it in portions and use the tail for recipes like this and for beef stroganoff.
