Kòng-Ôan, also known as bouncy meatballs, are typical Taiwanese street food items. These Taiwanese meatballs usually consist of highly seasoned, ground fatty pork mixture combined with chopped shiitake mushrooms, tapioca starch, baking powder, and egg whites.

The simmered meatballs are served piping hot, typically in a clear broth, and the dish is then garnished with chopped celery, cilantro, and fried shallots, or accompanied by noodles. These authentic Taiwanese meatballs are also sold in numerous Chinese markets throughout the U.S.
