Sirloin steak is a popular cut of beef that comes from the rear back portion of the cow. It is known for its balance of flavor and tenderness, making it a favorite choice for grilling and pan-searing. Sirloin can be divided into different types, including top sirloin and bottom sirloin, with the top cut being more tender. This cut is often leaner than other beef options, such as ribeye or T-bone steak, but still offers a rich taste. Sirloin steak is versatile and can be used in various dishes, from simple steaks to stir-fries and salads.
