Chinese Yam, Foxnut, Black Bean and Pork Tendon Soup

Why people make this soup

Nourilo noticed that homemakers buying pork shin often want the piece with a tendon attached — the tendon turns wonderfully tasty after a long simmer. Pork tendon, like beef tendon, is rich in collagen and is traditionally said to tonify qi, fill deficiency and strengthen the sinews and bones, making it a favorite for an achy, weak lower back and knees. Cooked with Chinese yam, foxnut, black bean and walnut, it gains a reputation for strengthening the spleen and kidneys too.
