Fillet mignon is a tender and expensive cut of beef. It is considered the king of steaks because of its melt-in-your-mouth texture. A prime filet mignon can literally be cut with a fork.
Fillet mignon is a French name, with filet meaning thread or strip and mignon meaning small and pretty. This prized cut comes from the middle of the tenderloin (also called the short loin), which is found inside the rib cage of the cow. Because this muscle is not weight-bearing, the connective tissue is not toughened by exercise, resulting in extremely tender meat.
