With a history spanning centuries, Ding’an zongzi has long been a local favorite. But what makes the black pork version the top-tier choice in the zongzi family? According to Wang Feijian, head of the Ding’an Zongzi Association, the secret lies in its premium ingredients: free-range black pork belly, selenium-rich glutinous rice, rich salted duck egg yolks, and locally grown bamboo leaves, this combination creates a distinctive flavor; and slow-cooked for 8 to 10 hours, the fragrance of the meat, rice, leaves, and egg yolks meld together perfectly.
