Canh chua

Canh chua (literally "sour soup") is a sour soup indigenous to the Mekong Delta region of southern Vietnam. It is typically made with fish from the Mekong River Delta, pineapple, tomatoes (and sometimes also other vegetables such as okra or bạc hà), and bean sprouts, in a tamarind-flavored broth. It is garnished with the lemony-scented herb ngò ôm (Limnophila aromatica), caramelized garlic, and chopped scallions, as well as other herbs, according to the specific variety of canh chua; these other herbs may include rau răm (Vietnamese coriander), ngò gai (long coriander), and rau quế (Thai basil). The sour taste of the soup comes from tamarind, which is mixed with a small amount of hot water; the mixture is then stirred for a few moments...
