Method
- Bring stock to a simmer in a wide pot. Whisk in tamarind paste; the broth turns cloudy amber.
- Add pineapple, tomato and taro stem. Simmer 10 minutes — the fruit and vegetables should soften and contribute their sweetness and acidity to the broth.
- Season with fish sauce and sugar. Taste — should be aggressively sour first, then salty, with the pineapple sweetness running underneath. Adjust tamarind for more sourness.
- Slide the fish pieces in carefully. Cook 4 minutes — pull off the heat the moment the flesh turns opaque. Overcooking turns the fish dry.
- While the fish cooks, fry the garlic: heat oil in a small pan, fry minced garlic 60 seconds until pale gold. The colour should not exceed amber — burnt garlic is bitter.
- Add okra and bean sprouts to the soup off the heat. Throw in the herbs (rice paddy herb, sawtooth coriander) and chilies. Drizzle the garlic-and-oil over the top. Serve immediately with rice on the side; canh chua is the soup of a multi-dish southern Vietnamese family meal, rarely the only thing on the table.

This recipe is written for 4 servings. To scale, multiply each ingredient proportionally; the cooking times stay the same up to about double the volume. Beyond that, expect to cook in batches because of pan size and heat distribution.
Cultural Note
Canh chua belongs to the Mekong Delta — the river-fish-and-tamarind broth is what locals drink to cool down in oppressive humidity. Rice paddy herb (ngo om) is the southern Vietnamese signature; the lemony-cumin note doesn't appear in northern Vietnamese cooking at all. The dish is always served as one component of a meal, with steamed rice and other dishes on the side; ordering canh chua as a stand-alone main in a Saigon home would mark the diner as foreign.
