Beef Knuckle Bones

The knuckle is the stifle joint — where the femur meets the tibia, one of the largest and most collagen-dense joints on the animal. Serious broth makers know it the way serious bakers know leaf lard: not the most obvious choice, but the one that produces a result nothing else quite matches.

What the knuckle contributes to a long simmer is structural. The cartilage and joint surfaces dissolve slowly into the surrounding liquid, releasing an extraordinary quantity of gelatin that gives a finished broth its body, its gloss, and the lip-coating quality that separates a great stock from a thin one. Where marrow bones add richness and fat, the knuckle adds architecture. A broth built around knuckle bones sets firmly when chilled — not a loose jiggle, but a solid gel that melts back into something luxurious when reheated.

Split through the joint with the cartilage surfaces left intact, these go straight into the pot. Roast them first at 400°F for 30 to 45 minutes for a darker, more complex result. Cover with cold water, add aromatics, and simmer low and slow for 8 to 24 hours. Add a canoe-cut marrow bone alongside for richness and you have built a broth worth bottling.

Each pack contains one split knuckle, 3.00 to 4.49 lbs.

Our femur bone ends are the natural companion in the same pot — cartilage-rich from a different joint, and together they produce more than either delivers alone. Our canoe-cut marrow bones add the richness and depth that the knuckle cannot. And our beef soup bones cover a mixed selection for everyday broth making.
