So what part of the cow is “London broil?” Technically, it’s not a cut of meat, but a method of preparing it by marinating it and then pan-frying (or broiling) it to medium rare. Wanna hear a good one? “London broil” is unknown in England. It was devised by Americans to tenderize flank steak, a meat that is normally quite tough; it morphed into “London broil” as a “cut” in butcher shops later on. True flank steak is from the wrong part of the cow for kosher consumers, but our kosher butchers cheerfully label just about any cut of meat that is lean (and not naturally tender) as “London broil.” So don’t ask what part of the cow it comes from. The answers will only confuse you. Suffice it to say that you can take this relatively inexpensive meat and give it the royal treatment.
Before baking this baby, you sear it without adding oil to the pan. No oil because there's enough liquid from the marinade, and it caramelizes nicely to make a delectable crust. Serve it rare to medium rare along with the roasted onions: elegant to the max! It’s a nice change for your Shabbos dinner menu, without much work.
This is the ultimate marinade that works incredible on London Broil and many other cuts of meat. The onions are an automatic bonus side dish that makes this recipe great for a special weeknight dinner, holiday feast or Shabbat menu.
