The sirloin steak is cut from the sirloin, the subprimal posterior to the short loin where the T-bone, porterhouse, and club steaks are cut. The sirloin is actually divided into several types of steak. The top sirloin is the most prized of these and is specifically marked for sale under that name.

Compared to meat from other cattle, Angus beef develops with excellent marbling. Marbling is the level of the intramuscular fat. Marbling has an effect of enhancing tenderness, flavor, and keeping the meat moist when it’s cooking, especially at high temperatures. Beef is often graded according to their marbling ability, with the highest marbling degree given to the Prime and AAA grades.
