Bife de chorizo is an Argentinian beef cut equivalent to the US New York strip steak, strip steak, sirloin, and top loin traditionally used for asado. It is a thick, juicy steak with a sizable layer of fat on top. It comes in several varieties, namely the bife de chorizo angosto (thin sirloin) and the bife de chorizo mariposa (butterflied sirloin).
