Beef Ground
80/20 isn't a preference. It's most of the recipe.
Grinding is a format, not a part of the animal. Beef goes through a plate and comes out as a bulk ingredient, and the single number that predicts how it cooks is the fat percentage. Which primal it came from matters far less than whether a fifth of the weight is fat.
The rest of the animal
Beef Ground comes from all over the animal rather than one section, so nothing is marked. Every region is a link to that primal. The full butcher chart puts beef, pork and lamb side by side.
Fat is not a garnish here, it is the cooking medium. As a patty heats, fat melts and moves through the lean, and whatever does not stay behind runs out. At roughly one fifth fat by weight there is enough to do that and still leave the meat moist. At one tenth there is not, and the same minutes on the same griddle give you something dry. The cook was not wrong; the ratio was.
The label tells you two separate things and shoppers read the wrong one. Under USDA rules, ground beef can come from anywhere on the carcass and may not have fat added; hamburger is the same product except that beef fat may be added. Both are capped at 30% fat, and neither may contain water, phosphates, binders or extenders. A name like ground chuck, ground round or ground sirloin is a different kind of claim entirely — it promises the primal, not the ratio. Chuck happens to land near 80/20 on its own, which is why it became the default burger grind, but you are paying for the name. A plain package at the same ratio cooks identically.
Do not salt it early. Salt dissolves myosin, the protein that makes meat grains stick to each other. Mix salt through a grind and let it sit and it binds into a springy, sausage-like texture — exactly what you want in meatballs, meatloaf and dumplings, and exactly what you do not want in a burger, where the pleasure is a loose, open crumb. Season the outside of the patty as it goes into the pan.
Cubed stew meat is a format too. A bag of it is often trim from several different muscles that soften at different rates, so half the pot is done while the rest is still tight. Buying a chuck roast and cutting it up yourself costs about the same, takes five minutes, and gives you one muscle behaving one way.
One place where this is a safety question, not a preference. Whole muscle carries bacteria on its surface, which is why a seared steak can be rare inside. Grinding takes that surface and distributes it through the entire mass, so the USDA figure for any ground meat is 160°F throughout. A rare burger is not the same risk as a rare steak, and no amount of sourcing changes the geometry.
How it eats
Texture comes from the plate size and the fat, not from the muscle. At a burger ratio it stays juicy and loose; leaner grinds turn firm and grainy and then chalky. The flavour is straightforwardly beefy — this is what you build a sauce on, rather than something you taste around.

Questions
Common questions
Is ground chuck better than the plain grind?
For a burger, usually not. The name guarantees which primal it came from, not the fat percentage, and the fat percentage decides how the patty cooks. Chuck sits near 80/20 naturally, so if the plain package is also 80/20 the two behave the same and one of them costs more.
What is the difference between hamburger and the plain grind?
One line in the USDA standard: hamburger may have beef fat added, the plain grind may not. Both are capped at 30% fat and neither may contain water, phosphates, binders or extenders. In practice, read the ratio rather than the word.
Why is pressing the patty such a bad idea?
Pressing squeezes out melted fat and the water it is carrying, and neither comes back. That hiss in the pan is the difference between juicy and dry leaving the burger.
Can I cook a burger medium-rare?
Not safely from a package. Grinding moves surface bacteria through the whole mass, so the USDA number is 160°F all the way through. A steak is safe rare because its interior was never exposed to the outside world; a patty's interior was.
