I have bought London Broil for years-and despite a few times of overcooking it-my family and other enjoy my marinade and has always been a hit. The issue is that after "googling" the cut of beef London Broil is-I am onky now realizing that I have never asked my butcher what cut it was and even when buying from a supermarket-never bothered to look at the lable to see what it said other than the sticker or sale ad that said "london Broil" My search says it could also be Flank steak which in my view is thinner and looks different than what I have customarily seen as London Broil. I know it is NO TENDER cut of beef but, if NOT overcooked it is not a chewy piece of leather and has a nice taste. I need to order 3 large London Broils for a party and want to know the best or ONLY cut name it could be referred to as. Confused.
