LONDON BROIL an idea
The first thing to know about "London Broil" is that it isn't a particular cut of beef. It CAN be flank steak, or it can be cut from the round, or leg muscles of the beef, but the best London broil is cut from the top round. When cooked using a Sous Vide Circulator, this cut of beef is as tender as any strip steak with flavor that will blow your mind!
