I have this monster London Broil I bought yesterday and I am looking for some ideas. In the past I have marinaded it in brown sugar and soy sauce mixture and then threw it in a hot cast iron skillet on the stove and cooked it medium rare to rare. They are good like that but can be tough. I am looking for some smoking ideas. I have some beef broth I am thinking about putting in a catch pan underneath to get some au jus but I am curious on temps and times. Also any spices or seasonings that will go well with it. Thanks for the help.
