What is Flat iron Steak?
The Flat Iron Steak is the infraspinatus muscle. It is excavated from the beef chuck subprimal. It is the second most tender muscle in the beef carcass.
This steak was developed from the Muscle Profiling Study by professor Dwain Johnson in 2002.
The Flat Iron Steak properties make it “as tasty and tender as more expensive steaks, yet affordable enough for the average family to enjoy on a regular basis, and it costs a lot less than a choice filet or strip steak,” Johnson says.
Since the steak is cut from the top muscle blade area, it also goes by the name of top blade steak.
This steak is a thin cut, about one-inch-thick, and has no bones to get in the way of
a great steak experience.
This piece of meat has an advantage that allows it to compete with other premium cuts at a much lower price.
If you’re wondering why this cut is cheaper than most retail steaks, the answer is simple.
It’s because the cut is located in the chuck of the beef, and sadly, most cuts from the chuck have a bad reputation.
Indeed, the chuck area has a significant amount of gristle -fibers and connective tissues- and almost no marbling, making it less tender than other cuts.
However, this preconception about chuck steaks is wrong. The flat iron steak’s tenderness is a great example of the intrinsic qualities of this chuck cut.
This undervalued cut has intermarbling properties that baste the steak from the inside as the fat slowly melts and forms into a golden sear on the outside.
