Although visually similar to other types of steamed
baozi, the dough of steamed
cha siu bao is unique since it makes use of both
yeast and
baking powder as leavening. This unique mix of leavening gives the dough of
cha siu bao the texture of a slightly dense, but fine soft bread.
Tangzhong, a water roux, is sometimes used to keep the bread soft over long periods of time and aids in improving the texture of the bao. An alternative version of the steamed char siu bao is a baked version. While the dough is very similar, the baked char siu bao is more similar to a baked bun with the same
char siu filling. It is often coated with an egg and sugar wash before baking, resulting in a slightly sweeter, more bready char siu bao. Encased in the center of the bun is tender, sweet, slow-roasted pork tenderloin. This
cha siu is diced, and then mixed into a syrupy mixture of
oyster sauce,
hoisin sauce, roasted
sesame seed oil,
rice vinegar,
shaoxing wine or dry
sherry,
soy sauce, sugar, and cornstarch. ==Philippine cuisine==
