Cheesy, that London broil was a top round. In some parts of the country, they call flank steak the same thing. I love the top round, it's so flavorful, but really benefits from the sous vide. That cut, I'd probably have left in there a minimum of 4 hours, maybe 6. But it's personal preference anyway! It looks like it was delicious and cooked to perfection!
Love me some flank/flap meat in the sous vide. 122* for 5 hours with a minute hit with a torch brings a delectable dinner to the table. Bonus - flap meat is significantly cheaper than the other options at Costco.
