Tri-tip is a cut of beef that comes from the bottom sirloin section of the cow. It is known for its triangular shape, which is where it gets its name. This cut is popular for its rich flavor and tenderness, making it a favorite for grilling and barbecuing. Often seasoned with spices or marinades, tri-tip can be cooked using various methods, including roasting or smoking. It is commonly served sliced against the grain, which enhances its tenderness. This cut is especially popular in California and is often associated with Santa Maria-style barbecue.
