Beef Round
The cheapest beef in the case, and the least forgiving.
The round is the rear leg — the muscles that push the animal along. Steady, repetitive work builds dense, fine-grained fiber and almost no marbling, so there is no internal fat to buffer a mistake. It is the leanest section of the carcass, and the one where five degrees of overcooking is the difference between good and dry.
On the animal
Every other region is a link to that primal. The full butcher chart puts beef, pork and lamb side by side.
Everything about this primal follows from a number that is close to zero: there is very little fat inside these muscles. Fat is what gives a rib steak its margin for error — it melts, it lubricates, it keeps meat tasting moist well past the point where the protein has squeezed most of its water out. Take the fat away and the margin goes with it.
That does not make the leg bad meat. It makes it meat with rules.
Cook it briefly, or cook it for hours. Never in between. Roasted to rare or medium-rare and rested properly, a leg roast slices beautifully. Braised for hours in liquid, it comes apart. Held anywhere between the two it goes grey, dry and grainy — and unlike the shoulder or the shank, extra time does not rescue it, because there is not enough connective tissue here to turn into gelatin.
Slice it thin, across the grain. The fibers are long and run in consistent directions through each muscle. This is where deli roast beef comes from, and that is not an accident: a thick slab of leg meat and a paper-thin slice off the same roast are not the same eating experience.
Salt it a day ahead. Lean muscle gains more from dry brining than any fatty cut does. Salt applied well in advance draws moisture to the surface, dissolves into it, and is drawn back in — meat seasoned all the way through, and slightly better at holding onto its water while it cooks.
A naming warning
"London broil" is not a cut of beef and never has been. It is a method — marinate, broil hot, slice thin across the grain — that ended up printed on labels, most often over meat from this part of the animal. It tells you nothing about which muscle is in the package. Read whatever is written next to it instead.
On price
There is a great deal of this on every carcass and not much competition for it, which is why it is cheap, and why so much of it disappears into ground beef and jerky — two places where lean is a virtue rather than a problem.
How it eats
Beefy but plain, firm rather than tender, and dry the moment you look away. Its real virtue is that it slices cleanly — this is the meat that holds together in thin sheets, which is why it tends to end up in sandwiches, salads and stir-fries rather than alone on a plate.

Questions
Common questions
Why did my roast come out dry at the same temperature that works for a steak?
Because temperature is not the only variable; fat content is. A marbled steak at medium-rare still has melted fat sitting between its fibers. A leg roast at the same reading has only water, and has already given up a good share of it. Pull lean roasts around ten degrees earlier than you would a marbled cut and let carryover finish the job.
Why is this the standard cut for jerky?
Fat. Fat does not dry — it goes rancid — so jerky wants the leanest muscle available, which is exactly what the leg is. Slice with the grain if you want it chewy, across it if you want it to break cleanly.
Can I make steaks out of it?
Yes, if you treat them as meat to be sliced rather than a steak to be cut with a knife at the table. Marinate, sear hard and fast, rest, then slice across the grain as thin as you can manage. Cooked as a slab and served whole, even the most tender muscle in the leg eats tough.
