where does the tri tip cut of beef come from
Tri-tip The tri-tip is a triangular cut of beef from the bottom sirloin sub primal cut, consisting of the tensor fasciae latae muscle. Untrimmed, the tri-tip weighs around 5 pounds. [1]
Filet mignon The tenderloin runs along both sides of the spine, and is usually harvested as two long snake-shaped cuts of beef. The tenderloin is sometimes sold whole. When sliced along the short dimension, creating roughly round cuts, and tube cuts, the cuts (fillets) from the small forward end are considered to be filet mignon. Those from the center are tournedos; however, some butchers in the United States label all types of tenderloin steaks "filet mignon." In fact, the shape of the true filet mignon may be a hindrance when cooking, so most restaurants sell steaks from the wider end of the tenderloin - it is both cheaper and much more presentable.
