Canh chua is a popular Vietnamese soup originating from the Mekong Delta region. It's characterized by its contrasting flavors - sour, sweet, and savory. The soup incorporates ingredients such as seafood (eel, shrimp, snakehead, catfish), tomatoes, okra, pineapple, tamarind, bean sprouts, and fresh herbs with a tangy flavor.
Traditionally, canh chua is served either with rice vermicelli noodles or with a side of steamed jasmine rice. There are numerous versions of the soup depending on the ingredients used in it - besides fish, it can be made with water spinach, chicken, bamboo shoots, mustard greens, pork, or beef.
