Canh chua is the Mekong Delta’s sweet-sour soup: a tamarind-soured broth balanced with sugar and fish sauce, loaded with pineapple, okra, tomato, and bean sprouts, with shrimp added at the very end so they stay tender. The broth should be clearly sour with sweetness and salt behind it — taste it before anything else goes in, and adjust.
This is a home-kitchen adaptation of a Mekong Delta soup, not a claim of regional authenticity or tradition.
Ingredients
Serves 6.
- 12 oz (340 g) large shrimp (16/20 count), peeled and deveined
- 6 cups (1.4 L) water
- 1 tbsp tamarind paste, dissolved in a little hot water, plus more to taste (tamarind strength varies hugely by brand — start at 1 tbsp, taste, and add more)
- 2 tbsp sugar
- 3 tbsp fish sauce, plus more to taste
- 1 cup fresh pineapple chunks (about 1/4 pineapple)
- 1 cup okra, sliced diagonally (about 8 pods)
- 1 large tomato, cut into wedges
- 2 cups bean sprouts
- 2 celery stalks, sliced diagonally (traditional bac ha, elephant ear stem, is hard to find outside Vietnamese markets)
- 2 cloves garlic, minced, plus 1 tbsp neutral oil for the garlic oil
- Cilantro and sliced scallions, chopped (rice paddy herb, ngo om, and sawtooth herb, ngo gai, are the classic finish when available)
- 1 Thai chile, sliced (optional)
For serving: steamed jasmine rice; extra fish sauce with sliced chile on the side.
Method
- Make the garlic oil. Heat the oil in a small pan over medium heat, fry the minced garlic until just golden (about 2 minutes), and transfer to a heatproof bowl. Set aside — this gets drizzled over each bowl at the end.
- Build the broth. Bring the water to a simmer in a large pot. Stir in the tamarind (dissolved first in a ladle of hot water so it disperses evenly), the sugar, and the fish sauce. Taste now, before anything else goes in: it should be clearly sour with sweetness and salt behind it. Adjust tamarind and sugar in small increments — the safe approach is to start at 1 tbsp tamarind and taste up, since overshooting makes the soup harsh.
- Cook the firm vegetables. Add the pineapple and okra; simmer 2 minutes. Add the celery and tomato wedges; simmer 2 minutes more.
- Add the shrimp last. Bring the soup back to a boil, add the shrimp, and cook just until they turn pink and opaque — about 2 minutes. Do not walk away; shrimp go from perfect to rubbery in under a minute past done. The shrimp must be fully opaque all the way through (145°F / 63°C) — no translucent centers.
- Finish. Remove from heat immediately. Stir in half the herbs. Place a handful of raw bean sprouts in each serving bowl and ladle the hot soup over them — the residual heat wilts them just enough. That is the intended texture, not an oversight.
- Serve hot over or alongside steamed rice, topped with the remaining herbs and a drizzle of garlic oil.
Tips and ingredient notes
- Tamarind strength: the critical variable. Seedless tamarind paste, concentrated tamarind pulp, and tamarind powder all sour differently, and brands differ within each type. Starting at 1 tbsp and tasting up is the safe approach.
- Sugar and fish sauce balance: canh chua is sweet-sour-salty all at once, and the right sugar amount depends on the tamarind actually used.
- Shrimp size: larger shrimp (16/20 count) are more forgiving on timing than small ones.
- Herbs: ngo om and ngo gai are the classic finish; cilantro plus scallions work when they are unavailable — the page names both options honestly rather than pretending the fallback is the original.
Storage and food safety
Allergen note: contains shellfish (shrimp) and fish (fish sauce). Shrimp must be cooked until fully opaque with no translucent centers — 145°F (63°C) (FoodSafety.gov). The broth must be brought back to a boil before the shrimp go in. Serve within 2 hours; refrigerate leftovers promptly and reheat until steaming hot.
