Australia Striploin, also known as porterhouse and sirloin, is a cut of beef steaks from the short loin from a cow. It consists of a muscle that does little work, the longissimus, making the texture very tender, although not as tender as the nearby tenderloin or psoas major. Although most of the people cook this on the grill, pan-seared is also delicious, you can even broil in the oven, sous vide, or air fry your steak. Contact us for more information.
