The absolute best cut to use is the Sirloin, situated above the rear end of the filet it is lean and has light marbling. The best cut is between the 5th and the 9th rib.
You can also use the Top Sirloin, the round central piece of the leg
Or the Rump Steak, a very tender cut of beef, located at the top of the leg just before the tail.
As a cheaper alternative, you can also use the Round but the meat will be chewy as it has more connective tissues than the choices above.
