Pork Knuckles and Soybean-Stick Soup

The combination of pork and soybean sticks makes this soup very rich and milky, and the smoked knuckle lends a good, deep flavor without making the soup too smoky. If you like, serve on the side a dip sauce of light soy sauce with a sprinkling of freshly ground Szechuan peppercorns or minced fresh coriander to offer a contrasting taste to the meat.
