The buns are wrapped in a dough, which sometimes gets bigger by rising (called a leavened dough), or they're wrapped in a dough which doesn't do this (called an unleavened dough). The buns are then steamed over boiling water to cook them.

It is possible to buy deep frozen Xiaolongbao worldwide, normally in special shops or supermarkets which sell ingredients for Chinese cooking.
