Because ovens were rare, Chinese cooks have been steaming their bread dough for thousands of years, most likely since wheat-milling technology arrived in northern China by way of the Silk Road. There are many ways to present the steamed bread, and the Chinese knack for stuffing it with a savory or sweet filling is perhaps the most well known and well loved. The filled buns, or bāo, are a delicious, convenient fast food in many parts of Asia, where you can buy them from street vendors and snack shops. Here in the States where stopping at a neighborhood bāo stand isn’t the norm, I make the buns myself in small batches and enjoy them for lunch or as road food, whether I’m driving or flying. They can be reheated until soft , allowed to cool, and then kept in a plastic bag until you’re ready to eat. Medium-size buns are the easiest to make, so you may want to start with those. After you’ve made buns with the various fillings presented here, create your own fillings. To make steamed rolls that can be used for mini sandwiches.
The best way to reheat left over buns is to steam them for 5 to 8 minutes. Left over buns can be refrigerated for up to a week or frozen for up to a month.
