Sirloin steak is a cut that comes from the lower part of beef ribs. It continues from the tenderloin (the place where the most prized steaks come from) and is a high quality cut with a lot of flavor, since these muscles still do a reasonable amount of work. Sirloin has more flavor than a number of other steaks, and is divided into several different subcategories.
The most valued of these steak types is probably the top sirloin. This cut is a little hard to find unless you are specifically looking for it – the majority of steak listed as sirloin will actually be bottom sirloin, which is a larger piece of meat, more readily available, cheaper, and tougher. The bottom sirloin is also connected to the sirloin tip roast, a good but somewhat tough roast that should not be eaten as a steak.
The tri-tip steak is a robustly flavored portion of the bottom sirloin, but is the leanest part, so it overcooks easily. Sirloin pin bone steak is cut from the front of the steak and contains an oval pin bone, while sirloin flat bone steaks can be identified by the pieces of backbone and hipbone they contain.
A sirloin round bone cut will have less bone than many other sirloin steaks, and also less fat. Sirloin wedge bone steaks are taken from the rear of the sirloin, and have a small bone in it, shaped like a wedge. You can find all kinds of sirloin steaks at your local market.
Sirloin cuts are usually leaner and not as tender and buttery as some of the higher end steaks, but their low price and deep flavor makes up for a lot. Prepare them with dry heat, such as pan-frying, grilling, broiling, or a similar high heat method. Remember to treat different parts of the sirloin appropriately – cooking perfect steak will depend a lot on what part of the sirloin you are trying to prepare.
Be sure to purchase sirloin steaks that are clear and red. When beef is exposed to oxygen, the usual purplish color turns bright read. Make sure sirloin steak is cold and the package is free from holes. Beef should feel firm, and the sell by date should be after the date you are purchasing it. Keep it in the coldest part of the refrigerator for three to four days, and trim external fat before cooking if you want to.
Your steak will be done to medium rare when the internal temperature is 145 degrees Fahrenheit, and well done at 165 degrees. Turn steak with tongs only, since forks can cause juices to escape, and allow steak to rest five to ten minutes before serving to preserve juices.
Steak should be broiled two to four inches from the heat source, and will take eight to ten minutes, while grilled; lightly oiled steak will take six to eight minutes. Pan-broiling takes a little longer – thirteen to fifteen minutes or so.
