I have done this multiple times and it is unbelievable. Figured I would throw this up so some of you can enjoy the recipe. Marinade: FOR THE MARINADE (makes about 5 1/2 cups): 16 oz (2 cups) salad oil 8 oz (1 cup) soy sauce 8 oz (1 cup) Worcestershire sauce 1 cup brown sugar 1/2 cup sesame seeds 1 tsp garlic powder 1 tsp. ground ginger 1/4 tsp dry mustard MARINADE INSTRUCTIONS: Combine all ingredients for marinade; blend together well. Place flank steak into marinade. Use small enough container to allow it to be completely covered by marinade. Marinade 24 hours minimum and not more than 4 days or flavor of the meat will be overpowered by marinade I marinated it for 30 hours to start. This is it after I pat dried it and then put it back in the fridge for 2-3 more hours to make sure it was dry. I then put olive oil, magic dust and montreal steak seasoning and put it in saran wrap and back into the fridge for 6 more hours. I put the meat into the freezer about 1 hour before I am ready to get it on the smoker so I can smoke it as long as possible. I have the guru, so when the smoker is closed up, I throw the meat on with the wood. I got about an hour of good smoke on it. I kept the smoker at 160 until the meat got to 100 and then transferred it to the hot grill. I run the temp to 115 internal, flip and pull at 130 and cover in foil for 15 minutes. I put it on foil because I really wanted to clean my grates but ran out of time. Then to the grill for a good sear and to finish it off to medium rare. I nailed it, and the flavor was unreal. I am not fussing with the recipe on this one...I am leaving it just like it is.
