About 1 inch thick, one whole knuckle per pack, roughly 1 lb. Joint bones with cartilage that breaks down over long cooking into a thick, nutritious broth.

Roast at 400°F for 30 minutes first to deepen flavor, then simmer in a large pot for 8–12 hours. Or pressure cooker for 3–4 hours. Makes a deeply flavored, gelatinous stock that gels solid when chilled.
Will last 2-3 days in the fridge when fresh or once thawed. Will last up to 6 months frozen.
