I hear you. You bite into a Reuben sandwich and think, “This texture is too tender. This is definitely not a grass-fed wrestler. A pig must be involved.” Wrong. Your confusion is understandable because humans are terrible at meat-identification. The brisket is a heavily worked muscle, which means it’s tough and full of connective tissue. That’s why you don’t grill it—you braise it for hours. The long, slow cooking in water, spices (like bay leaves and peppercorns), and salt breaks down the collagen into gelatin, making it fall-apart tender.
It’s the same muscle cows use to walk up hills. Think of it as a cow’s quadriceps, but for walking. After a day of stewing, it tastes buttery, almost like a pork shoulder, but it’s 100% bovine. If you want to test this, do a blind taste test at your next barbecue. Bet you five dollars someone guesses “pork.” They will lose money and dignity.

The “Can of Mystery” Factor
Let’s also address the tinned version. The one that comes in a rectangular can with a key that always breaks. That is still beef, but it’s often a lower-grade cut or a mix of brisket pieces that have been chopped, compressed, and gelatinized into a loaf. It’s like the hot dog of the corned beef world. Do I love it? Yes. Do I know what’s really in it? I choose ignorance. The point is, from a can or from a butcher, the animal is always a cow. A Bos taurus. A mooer.
But here’s a truly bizarre fact: corned beef is almost always made from steer or heifer—young, castrated male or female cattle. Why? Because older, tougher bull meat tastes like regret and a leather shoe. The perfect corned beef comes from a relatively young animal that ate a lot of grass and never worked out. You are eating the lazy jock of the cow world.
