Could not find much info on flank steaks unless your making jerky so I thought I would pass this on. Put sweet rub and worchesteire sauce on 1.5 lb. Let sit in fridge for an hour and them smoked for 1.5 hours in hisckkory chips. Then turned up heat to 375 for 15 minutes to finish. After resting, I cut the meat. Nice red strip in a medium to medium rare piece of meat. Very tender and good flavor from rub and worchestaire. The smoke flavor in combination with the other flavors made for an excellant piece of meat.I will try this one again.
