Cha siu bao
Cantonese barbecue-pork-filled bun

Cha siu bao (simplified Chinese: 叉烧包; traditional Chinese: 叉燒包; pinyin: chāshāo bāo; Jyutping: caa1 siu1 baau1; Cantonese Yale: chā sīu bāau; lit. 'barbecued pork bun') is a Cantonese baozi (bun) filled with barbecue-flavored cha siu pork. They are served as a type of dim sum during yum cha and are sometimes sold in Chinese bakeries.
Varieties
There are two major kinds of cha siu bao: the traditional steamed version is called 蒸叉燒包 (pinyin: zhēng chāshāo bāo; Jyutping: zing1 caa1 siu1 baau1; Cantonese Yale: jīng chāsīu bāau) or simply 叉燒包 (chāshāo bāo; caa1 siu1 baau1; chāsīu bāau), while the baked variety is usually called 叉燒餐包 (chāshāo cān bāo; caa1 siu1 caan1 baau1; chāsīu chāan bāau). Steamed cha siu bao has a white exterior, while the baked variety is browned glazed.
Cantonese cuisine
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.

Why this record matters
The subject matters to the general reference register because the source frames it as cantonese barbecue-pork-filled bun. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 31, 2026. The linked authority identifier is Q1207732. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
