Keke pua'a

Cha siu bao 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. 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 and glazed.
