Etymology: According to the National Cattlemen’s Beef Association, this steak is marketed under various names, including Ambassador Steak, Club Steak, Hotel-Style Steak, Veiny Steak, Kansas City Steak and New York Strip Steak. Delmonico’s offered Strip as a signature dish way back in the early 1800’s. Due to the cut’s association with NYC, the New York Strip Steak name was born.

Anatomy: The Strip is cut from the other side of the tenderloin, across the vertebra on the T-bone or Porterhouse.

Also known as strip loin, the Strip Steak is cut from the short loin part of the animal, from a muscle that does little work, like the Filet Mignon. It is generally more tender than the similarly situated but more posterior-located sirloin section of the animal. While it is essentially the same kind of meat as sirloin, the muscles in the rear do a bit more work than the short loin, so can be a bit more tough.

Preparation: For me, the Strip is best at medium rare, to preserve the tenderness and reduce any mealy or grainy textures that can develop from overcooking. It is always best to get a really great quality cut for this chop, something prime+, as all the intra-muscular fat, or marbling, will become soft and the muscle will tenderize all over.  You will often see it marinated or rubbed with spices, to impart additional flavors, but grilling and broiling in the traditional style is fantastic as well, especially with butter and herbs.  It can be served bone-in or boneless. Leaving the bone in will impart more flavor and help with the cooking process, since the bone conveys heat into the center of the meat while locking in juices.  At home, marinade this puppy in something like soy sauce and garlic, and slap it on the BBQ for a few minutes on each side and you will have the perfect home-cooked steak.

Flavor: This cut contains fat in levels that are somewhat in between the tenderloin (virtually none) and the Rib Eye (plenty of good, melty fat). Like the tenderloin, there is little variation throughout the cut, so the flavors and textures are more uniform for the Strip Steak, unlike the Rib Eye which has varying textures and flavors from one end of the cut to the other. The texture of a Strip can sometimes be a little bit grainy or mealy, and a bit more tight than a Filet Mignon or a Rib Eye – especially if it’s cooked too much.

Etymology: Filet, in culinary terminology, means boneless. Mignon, in French, means dainty or small. As such, this is a steak ideally suited for chicks: small/dainty, and with no bone.

Occasionally on a steakhouse menu you will see a “bone-in filet.” Given what I just mentioned above, that phraseology is completely self-defeating and confusing, as it simultaneously means both “bone-in” and “boneless.” However, it seems this sort of language is becoming commonplace. If it were up to me, I would prefer “bone-in tenderloin” to be listed on menus instead. There is no wording conflict with that phrasing, and it is an accurate description of what is being presented. In other words: all Filet Mignon is tenderloin, but not all tenderloin is Filet Mignon.

Anatomy: Traditionally, a Filet Mignon was cut from the anterior end of the tenderloin. In the beef chart image below, you can see a portion of the tenderloin section highlighted in red.

That is where Filet Mignon was typically located, though most butchers label all steaks cut from the tenderloin as Filet Mignon (this allows for larger portions). The tenderloins run along both sides of the spine. They taper from thick, in the posterior of the animal, to thin in the front.

In their unbutchered form, they contain what’s called the “silver skin” still attached to the flesh. This is a thick connective tissue that is pretty much inedible. When butchering the full tenderloin, you will want to slice that off (it is NOT tender).

While this next photo is a repeat shot of a lamb vertebra Barnsley chop (the mutton chop from Keen’s), the anatomy is exactly the same for beef. This will illustrate exactly where the filet comes from. Essentially this is a double porterhouse, with a filet and a strip on each side. In addition to understanding the Filet Mignon, this image is useful in demonstrating the anatomy of the Strip and Porterhouse cuts as well, since they all come from the same place – the vertebrae of the animal:

Preparation: Preparations of this cut vary greatly. You may see this cut sliced thin and pounded flat, served raw for carpaccio. You may also see it finely chopped for tartare. A simple pan sear with butter and herbs, however, is probably the most common preparation.

Yet another style is Chateaubriand, which is a large section of the thick portion of the tenderloin that is roasted boneless, then sliced and served with a reduction sauce.

There is also Beef Wellington, which is a portion of tenderloin that has been coated with pate and then wrapped in puff pastry dough prior to cooking.

Flavor: Widely considered the most tender and least fatty cut of beef on the animal, the flavor should be uniform from one end to the other, with very tender and soft texture the whole way through. There is hardly any fat content in the standard cut of Filet Mignon. Some chefs will wrap the filet in caul fat (a lacy, fatty, web-like membrane that surrounds the stomach of an animal) before cooking. The webbing melts away during cooking and imparts a fat flavor into the meat. But it is more common to use things like butter, or to wrap a filet in bacon to add the fat flavor into the meat.

Etymology: There is some difference of opinion on the origin of the word “Porterhouse,” with several restaurants and cities claiming to have created the name. For example, Martin Morrison served large T-bones in his Pearl Street (Manhattan) “Porter House” around 1814. This history was popular in the late 1800’s, but some say a Cambridge, Massachusetts proprietor by the name of Zachariah B. Porter added his name to the steak. Still, others argue that the Porterhouse name stems from various 19th Century U.S. hotels or restaurants called Porter House, such as the Porter House Hotel in Flowery Branch, Georgia.

Anatomy: The Porterhouse is a cut of steak from the short loin portion of the animal that contains both strip loin and tenderloin meats. See the highlighted portion in the diagram below:

It is cut from a lumbar vertebra that is sawed in half through the vertebral column.

The downward prong of the “T” is a transverse process of the vertebra, and the flesh that surrounds it (spinal muscles) makes up the meat of the Porterhouse.

Essentially, it is a large T-bone steak from the rear of the animal that has two different types of meat (tenderloin and strip loin), one on either side of the “T.” In the picture below, the strip loin or Strip Steak is on the right, and the tenderloin or Filet Mignon is on the left.

The small semicircle at the top of the ‘T’ is half of the vertebral foramen, which is the name of the hole that passes through each vertebra for housing and protecting the spinal cord. They run the whole way up the back, all the way up to the brain of the animal.

The anatomy of a Porterhouse differs from that of a T-bone only in that the Porterhouse contains a larger portion of tenderloin than its T-bone counterpart.

This is primarily due to the fact that Porterhouse steaks are cut from further in the rear of the animal, from lumbar vertebrae, where the tenderloin is much thicker. Experts differ, however, on how large the tenderloin must be to differentiate a Porterhouse from a T-bone. The U.S. Department of Agriculture’s Institutional Meat Purchase Specifications state that the tenderloin of a Porterhouse must be at least 1.25 inches thick at its widest, while that of a T-bone must be at least 0.5 inches.

Here is a shot of a short loin with multiple vertebrae still intact and not portioned out into individual Porterhouses and T-bones.

You can see on the left there is a good sized, thick portion of tenderloin. That thins down as you move the the right, and seems to disappear by time your eyes reach the far end of the cut.

Just to drive home the anatomy a little more, here is a great excerpt and image from Russ Cooks:

“Up close and personal, this is where the T-bone fits.

The black line across the top of the two T-bones pictured here is the outside (top of the back) of the steer. You can see the T-bone in the schematic illustration higher up on this page as the topmost part labelled Rib. Above the ribs, what you touch if you pat the steer’s back, is the New York strip. Beneath the ribs is the tenderloin from which a filet mignon is often cut. T-bone steaks cut closer to the shoulder are known as Porterhouse while those cut closer to the loin are just T-bones.”

Preparation: Most times, T-bones and Porterhouses are either grilled, seared in a pan, broiled or blasted with high heat in specialty steak ovens made for charring the outside of the meat without over-cooking the inside. Butter is essential, and heavy seasoning is important as well. Herbs and garlic help boost the flavor too.

Flavor: Since this cut contains both the Filet Mignon and the Strip Steak, I refer you to the flavor sections for those cuts below, with a notation that the bone being left in often adds a more robust flavor while helping to retain tenderness and juiciness. These are very popular items at steakhouses because they can be cut large enough to feed anywhere from two to four people. Additionally, with two different types of meat in one steak, one can vary the flavors that one experiences with each bite.
