How 9 Cuts of Meat Got Their Names

Original image

Ever find yourself standing in front of a butcher's counter and wonder where in the world certain cuts and preparations of meat got their names? Here are the stories behind a few popular meals.

1. Boston butt

Don't be too grossed out when you hear this name; it doesn't mean "butt" as in "rear end." Instead, the cut comes from the front shoulder of the pig. So why "butt"? During colonial days New England butchers tended to take less prized cuts of pork like these and pack them into barrels for storage and transport. The barrels the pork went into were called butts. This particular shoulder cut became known around the country as a New England specialty, and hence it became the "Boston butt."

2. Porterhouse steak

The origin of the term "porterhouse" is surprisingly contentious, as several cities and establishments claim to have coined it. The name might have originated on Manhattan's Pearl Street around 1814, when porter house proprietor Martin Morrison started serving particularly large T-bones. The Oxford English Dictionary lists this etymology as the likely origin of the steak's name while noting that there's no contemporary evidence to support or contradict the tale.

This origin story gained traction in the late 19th century, but other carnivores contend a Cambridge, Mass. hotel and restaurant proprietor named Zachariah B. Porter lent his name to the cut. Still others claim that the steak takes its name from the Porter House, a popular 19th-century hotel in Flowery Branch, Ga.

3. Filet mignon

The term filet mignon is French for "dainty fillet." Somehow this makes eating one seem a bit less manly, although no less delicious.

4. Canadian bacon

When you chomp into a slice of pizza with Canadian bacon on it, are you sending a little bit of culinary support to our neighbors to the north? Not quite. Canadian bacon is simply a leaner, brined type of bacon that comes from a loin cut further back on the pig. Americans started calling this type of pork "Canadian bacon" because we were under the impression that Canadians particularly loved their back bacon.

5. Swiss steak

At least Canadian bacon has some theoretical tie back to the Great White North. Swiss steak, the bane of school cafeterias everywhere, has nothing to do with Switzerland. Instead, the term "Swiss steak" refers to the meat having gone through a process called "swissing" before being cooked. Swissing, which is also used in textile production, refers to a process of hammering, pounding, or rolling a material to soften it up. In the cast of Swiss steak, butchers take tough cuts of beef and pound them or roll them to make them tender.

6. Hanger steak

The bistro favorite is so named because it "hangs" from the diaphragm between the rib and the loin of the steer from which it is cut.

7. Chateaubriand steak

This preparation for a thick cut from the tenderloin allegedly takes its name from the first diner to enjoy it, Vicomte Francois-Rene de Chateubriand (1768-1848). Chateaubriand was a foodie, but he got quite a bit done away from the dinner table, too. He served as France's ambassador to Prussia, and his writing earned him praises as the father of French Romanticism.

Chateubriand enjoyed a good steak, too. At some point during his life, the writer's personal chef whipped up a dish of a very large peppered beef tenderloin topped with a buttery wine-and-shallot sauce, and a new meat sensation was born.

8. 7-Bone roast

Don't let the name fool you; this isn't a particularly bony piece of beef. The 7-Bone roast actually comes from a cross cut of a cow's shoulder blade, which leaves a large bone shaped like the number seven in the meat. Although it's not as bony as you'd think, it's not a particularly easy cut to cook. It's generally so tough that it's best for braising.

9. Flat iron steak

This trendy, tasty cut is a fairly recent development. In the early 21st century meat science professors at the University of Nebraska and the University of Florida searched cattle with a fine-toothed comb in the hopes of finding an exquisite new cut they could bring to market. After much research, they found an underappreciated muscle in the shoulder that would provide a delicious, well-marbled piece of beef if cut correctly. The new cut was dubbed the "flat iron steak," supposedly because it is shaped somewhat like an old-fashioned flat iron.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

8 Common Dog Behaviors, Decoded
May 25, 2017

Dogs are a lot more complicated than we give them credit for. As a result, sometimes things get lost in translation. We’ve yet to invent a dog-to-English translator, but there are certain behaviors you can learn to read in order to better understand what your dog is trying to tell you. The more tuned-in you are to your dog’s emotions, the better you’ll be able to respond—whether that means giving her some space or welcoming a wet, slobbery kiss. 

1. What you’ll see: Your dog is standing with his legs and body relaxed and tail low. His ears are up, but not pointed forward. His mouth is slightly open, he’s panting lightly, and his tongue is loose. His eyes? Soft or maybe slightly squinty from getting his smile on.

What it means: “Hey there, friend!” Your pup is in a calm, relaxed state. He’s open to mingling, which means you can feel comfortable letting friends say hi.

2. What you’ll see: Your dog is standing with her body leaning forward. Her ears are erect and angled forward—or have at least perked up if they’re floppy—and her mouth is closed. Her tail might be sticking out horizontally or sticking straight up and wagging slightly.

What it means: “Hark! Who goes there?!” Something caught your pup’s attention and now she’s on high alert, trying to discern whether or not the person, animal, or situation is a threat. She’ll likely stay on guard until she feels safe or becomes distracted.

3. What you’ll see: Your dog is standing, leaning slightly forward. His body and legs are tense, and his hackles—those hairs along his back and neck—are raised. His tail is stiff and twitching, not swooping playfully. His mouth is open, teeth are exposed, and he may be snarling, snapping, or barking excessively.

What it means: “Don’t mess with me!” This dog is asserting his social dominance and letting others know that he might attack if they don’t defer accordingly. A dog in this stance could be either offensively aggressive or defensively aggressive. If you encounter a dog in this state, play it safe and back away slowly without making eye contact.

4. What you’ll see: As another dog approaches, your dog lies down on his back with his tail tucked in between his legs. His paws are tucked in too, his ears are flat, and he isn’t making direct eye contact with the other dog standing over him.

What it means: “I come in peace!” Your pooch is displaying signs of submission to a more dominant dog, conveying total surrender to avoid physical confrontation. Other, less obvious, signs of submission include ears that are flattened back against the head, an avoidance of eye contact, a tongue flick, and bared teeth. Yup—a dog might bare his teeth while still being submissive, but they’ll likely be clenched together, the lips opened horizontally rather than curled up to show the front canines. A submissive dog will also slink backward or inward rather than forward, which would indicate more aggressive behavior.

5. What you’ll see: Your dog is crouching with her back hunched, tail tucked, and the corner of her mouth pulled back with lips slightly curled. Her shoulders, or hackles, are raised and her ears are flattened. She’s avoiding eye contact.

What it means: “I’m scared, but will fight you if I have to.” This dog’s fight or flight instincts have been activated. It’s best to keep your distance from a dog in this emotional state because she could attack if she feels cornered.

6. What you’ll see: You’re staring at your dog, holding eye contact. Your dog looks away from you, tentatively looks back, then looks away again. After some time, he licks his chops and yawns.

What it means: “I don’t know what’s going on and it’s weirding me out.” Your dog doesn’t know what to make of the situation, but rather than nipping or barking, he’ll stick to behaviors he knows are OK, like yawning, licking his chops, or shaking as if he’s wet. You’ll want to intervene by removing whatever it is causing him discomfort—such as an overly grabby child—and giving him some space to relax.

7. What you’ll see: Your dog has her front paws bent and lowered onto the ground with her rear in the air. Her body is relaxed, loose, and wiggly, and her tail is up and wagging from side to side. She might also let out a high-pitched or impatient bark.

What it means: “What’s the hold up? Let’s play!” This classic stance, known to dog trainers and behaviorists as “the play bow,” is a sign she’s ready to let the good times roll. Get ready for a round of fetch or tug of war, or for a good long outing at the dog park.

8. What you’ll see: You’ve just gotten home from work and your dog rushes over. He can’t stop wiggling his backside, and he may even lower himself into a giant stretch, like he’s doing yoga.

What it means: “OhmygoshImsohappytoseeyou I love you so much you’re my best friend foreverandeverandever!!!!” This one’s easy: Your pup is overjoyed his BFF is back. That big stretch is something dogs don’t pull out for just anyone; they save that for the people they truly love. Show him you feel the same way with a good belly rub and a handful of his favorite treats.

The best way to say “I love you” in dog? A monthly subscription to BarkBox. Your favorite pup will get a package filled with treats, toys, and other good stuff (and in return, you’ll probably get lots of sloppy kisses). Visit BarkBox to learn more.
