Besides plain buns, “Zanbo Handmade Baozis and Steamed Buns” also have cranberry buns and wheat buns. The cranberry buns are made by mixing cranberries with the dough, having a distinct flavor; and wheat buns are made by mixing whole wheat flour, five grains (or cereals), raisins and dough. It is worth mentioning that Zanbo keeps part of the fermented dough in the fridge as “old dough,” which is then mixed into the new dough the next day to make baozis and steamed buns. The baozis and steamed buns mixed with “old dough” have a special flavor and aroma.
