Strips of lamb or beef tripe dipped in boiling water for a few seconds, so they stay crunchy and chewy, eaten with a sesame paste sauce. A Beijing snack.
Beijing snack-shop classic: thin strips of beef or lamb tripe are scalded in boiling water for just a few seconds (爆 = explosive or flash heat), then dipped in sesame paste with chive flower sauce, fermented bean curd and chili oil. Famous old shops include 爆肚冯 and 爆肚满 in the Niu Jie / Houhai area.
