Mixed bones left over from butchering, mostly pork, sold by weight with some meat still on them. They are blanched to clean them, then simmered for a long time as a soup base.
This shop's assorted bones are cheap and make fragrant broth.
Tips
usage
杂骨 is a colloquial butcher/market term for mixed leftover bones sold cheaply for broth-making. Not a formal lexical entry, mostly encountered in cookbooks, meat-counter signs, and recipe contexts rather than dictionaries.
