Steam buns (aka Bao) have a long history in Chinese cuisine, with some historians dating them as far back as 700-400 BC. While their history may be long, they are a relatively new favorite to Westerners. In large cities, you’ll find restaurants and food carts dedicated to these deliciously filled buns. If you don’t have access to one of these bao specialists, no fear. You can now easily make them at home! This recipe is for ground pork bao, but you can easily change the filling to your favorite protein.
