Siu haau (Chinese: p=shāokǎo) sauce is the primary barbecue sauce used in Cantonese cuisine. It generally contains garlic, honey, palm sugar, five-spice powder, and pepper.[1]
Siu haau is used during the barbecue-cooking process as opposed to a flavoring sauce after the food is made. It is not used for siu mei rotisserie-style cooking; dishes such as char siu each have their own sauce.
