Xiaolongbao is more often known in Shanghai and its surrounding areas as “xiaolong manto” (pinyin). "Mantou" describes both filled and unfilled “baozi” in southern China, but only describes unfilled “baozi” in northern China. To avoid confusion, the name xiaolongbao is usually used in other areas. It is traditionally steamed in bamboo steamers, hence the name is awarded.
Xiaolongbao in Wuxi taste sweeter and have a thinner dough skin, and are juicier than the Shanghai variety.
