London Broil

London Broil is a recipe term that describes a flank steak which has been broiled and cut on the bias for serving.  While you may even see a steak in the market named London Broil it is really just the common flank steak. 

The recipe dates back to the 1930's but the only thing British about it is in the name. This is an exclusively American invention.

You can use skirt steak instead of flank steak
