Koah-pau

Koah-pau or gua bao or cuapao also known as a pork belly bun, ambiguously as bao, or erroneously as bao bun, is a type of lotus leaf bun originating from Fujianese cuisine in China. It is also a popular snack in Taiwan, Singapore, Malaysia, the Philippines, and Nagasaki Chinatown in Japan. It consists of a slice of stewed meat and condiments sandwiched between flat steamed bread known as lotus leaf bread (荷葉餅; héyèbǐng). The lotus leaf bread is typically 6–8 centimetres (2.4–3.1 in) in size, semi-circular and flat in form, with a horizontal fold that, when opened, gives the appearance that it has been sliced. The traditional filling for gua bao is a slice of red-cooked pork belly, typically dressed with stir-fried suan cai (pickled mustard greens), coriander, and ground peanuts.
