Comments

It is my understanding that a sirloin roast is called a tri-tip roast. The boneless sirloin tip is also called top sirloin, triangle and loin tip . The better grades can be oven-roasted; otherwise moist-heat methods should be used.

(A bottom round roast is called a tip roast. Look for recipes for that, or use a tri-tip recipe with your sirloin roast.)
