Pork floss is a popular topping in Macau cuisine. It is made by stewing pork until it becomes tender and then shredding it into fine strands. The shredded pork is then seasoned with spices and dried until it becomes a fluffy and flavorful topping. Pork floss is often used as a topping for rice, noodles, and congee, adding a savory and textural element to the dishes.
