Have made this a few times now. Great with the recommended soba noodle salad. Definitely a keeper.
The whole family love this steak. We did think that the flavor would be much better and stronger if the steak were allowed to marinate in the hoisin glaze overnight before grilling, but it was still delicious. You can read my full review at Taking On Magazines: http://bit.ly/11H0tWR
Made exactly as directed, using sirloin based on first review. Very tender and flavorful but needs some tweaking. I tasted a bit too much hoisin so will decrease to 2 Tbs. next time. The vegetable salad was great. I added some celery as it was on hand, doubled the rice vinegar and added 1 tsp. sugar. I would rate the veggies as four star themselves.
Flank steak is too tough for our taste. I will substitute sirloin or top round in the future, and perhaps tenderize before grilling. We also thought the flavorings could be intensified a bit. Overall this recipe has lots of potential, and I'll tweak it and serve it again.
