London Broil is an EXCELLENT cut if done right! First, you can't really think of it as a steak. If you just cut chunks off and eat it that way, it'll be tough as leather even if prepared well. First, marinate it (you choose the ingredients or marinade, I'm not going into that, it's all opinion/individual taste). I hope you aren't into well done beef, because that'll kill a London Broil. I personally won't cook one past medium, so if anyone is eatiing that likes their steak ruined/burned (i.e. past medium), I won't do a London Broil. Anyway, you need to cook it quickly over hot coals (or high setting if you use a gas grill). How long will depend on how thick it is and how done you want it. There are numerous on line guides for that sort of thing. Personally, I usually like one that's about 1 1/2" thick, and about 4 minutes per side, maybe 5 on one side. After you pull it off the grill, you MUST let the meat rest for about 5 minutes. When you slice it (yes, slice it, like a roast), cut across the grain, into thin slices. THAT'S how it becomes a nice tender juicy tasty cut of beef. As I always do, I'll suggest looking at http://www.allrecipes.com. I consider myself a pretty good cook, and I consult that site all the time for recipes and tips.My family loves London Broil. I marinade it in Adolf's Meat Marinade (2 packages) for several hours. Using a large fork poke holes in both sides of the meat. Prepare the marinade according to the package directions and place meat and marinade in a zip lock bag. I prepare the meat the night before I am fixing it for dinner the next evening. I then broil it in a cast iron pan, in the marinade, for about 8 minutes on each side (medium rare). Remove from marinade, place on your cutting board, cover with foil and let rest for at least 10 minutes. This allows the juices to go back into the meat so it will be juicy when you slice it. Slice on an angle in very thin slices. I serve this with saffron rice and green peas. The cooked marinade is now a delicious sauce you can serve over the meat and the rice. You can purchase London Broil at your local supermarket much cheaper than over the internet. The store butcher can help you with your selection. Good Luck!
