Flat iron steak
From Wikipedia, the free encyclopedia
The Flat iron steak is a relatively new cut of steak from the shoulder of a cow. The steak was discovered by researchers at the University of Nebraska and the University of Florida during the course of a study of undervalued cuts of beef. The major barrier to the flat iron steak was the large band of connective tissue running down the center of the steak, which led people to assume that the cut in general must be tough. Removing the connective tissue, however, leads to a steak that is often described as having both the tenderness of a rib eye or strip steak while still having the earthy character of a sirloin or skirt steak.
You may see this cut of meat displayed in some butcher shops and meat markets whole as a "chuck tender" roast as some meat cutters call this cut a "chuck tender" in its' whole form. As a whole cut of meat it weighs usually around 2 to 3 lbs, is located in the larger portion of the chuck and can be removed from the larger chuck almost without a knife.
Restaurants, particularly upscale, have recently begun serving flat iron steaks on their menus.
Many recipes suggest marinating the flat iron steak before cooking.
Another way to use this cut is to remove the connective tissue strip, then butterfly sections similar to a filet mignon and wrap them in bacon. Although not in the same category texture or taste wise as a filet mignon (tenderloin) it is nonetheless appetizing, especially after marinating.
Rather precise instructions for how to cut this piece out from the shoulder can be found in Bruce Aidells' "The Complete Meat Cookbook" - pp. 134-35 ISBN 0395904927
Joe is right that chicken fried steak is an inexpensive cut of meat, often round, that is pounded flat and pan-fried.
