Sirloin tri-tip roast de John Spottiswood

This is a very flavorful cut that's great for barbecuing as long as you take pains to keep the meat from getting too tough. The trick is to not trim the fat until the roast is cooked so that the juices can tenderize the meat. When it's done, slice it thinly against the grain. This cut is popular in California, but you might have trouble finding it elsewhere. A steak cut from this roast is called a tri-tip steak.
