London Broil Okay, one recipe! London Broil cooks on broil, remember that is when only the top burner of the oven lights up, so don't put it to close and remember to turn it over to cook on both sides. For London Broil, I buy top round london broil and usually you can look at it and say, "yeah it will feed both of us". See Becky Crocker book for cooking times.
