Posole is not just a soup, it’s an event: a big hearty bowl of goodness, sumptuous and filling, and totally worth the effort of a couple of extra steps. The bones are essential; use bigger ones so they are easier to handle at the end. I like to cook a bone-in pork shoulder for this and use the big blade bone. The pork hock adds subtle smoky notes, while the beef bones or oxtails add to the soup’s complexity. Frying the chile puree improves the flavor of the soup, so don’t skip this step.
