Char siu is a Chinese, specifically Cantonese–style of barbecued pork. Originating in Guangdong, it is eaten with rice, used as an ingredient for noodle dishes or in stir fries, and as a filling for chasiu baau or pineapple buns. Five-Spice Powder is the primary spice, honey or other sweeteners are used as a glaze, and the characteristic red color comes from the red yeast rice when made traditionally.
It is classified as a type of siu mei (燒味), Cantonese roasted meat.
