The tenderest cuts of beef come from the aptly named tenderloin. And, when you look at the price of the most desirable center portions of tenderloin, filet mignon and Chateaubriand, they are also the most expensive cuts of beef.
However, the tenderloin also yields cuts that, by comparison to the filet and Chateau, are less expensive yet have the same tenderness and flavor as the prized center cuts.
The shape of the tenderloin tapers from the head (large end) to the tail (small end). Both ends can be roasted, sliced into small steaks, or cut into cubes or strips for kabobs, stir frys, stroganoff, and so much more.
So, with a couple of sharp knives and a game plan, buying a whole tenderloin is a comparatively economic way to enjoy of range of meals with some simple home butchering skills.
