Ingredients

• 2 ounces tamarind pulp
• 1 cup boiling water
• 1 tbsp neutral oil
• 2 cloves garlic – minced
• 1 piece bird’s eye chili – thinly sliced (optional)
• 6 cups water
• 3 tbsp fish sauce
• 2 tbsp sugar
• 0.5 tsp salt
• 1.5 pounds catfish steaks
• 2 cups pineapple – cut into 0.75-inch chunks
• 8 pods okra – sliced 0.5-inch thick
• 2 cups elephant ear stem (bac ha) – peeled and sliced 0.5-inch thick
• 2 pieces tomatoes – cut into wedges
• 2 pieces scallion – thinly sliced
• 2 cups bean sprout – for serving
• 0.5 cup rice paddy herb – coarsely chopped (for serving)
• 0.25 cup sawtooth herb – chopped (for serving)

Instructions

1. Combine tamarind pulp with the boiling water in a bowl and let soak until soft, 10 minutes. Mash well, then strain and reserve the tamarind liquid; discard solids.
2. Heat the neutral oil in a 4-quart pot over medium heat. Add the minced garlic and bird’s eye chili (if using) and cook until fragrant, 30–60 seconds; do not brown.
3. Pour in the 6 cups water and the reserved tamarind liquid. Bring to a boil over high heat, then reduce to a gentle simmer. Skim any foam.
4. Stir in the fish sauce and sugar. Taste the broth; it should be bright-sour with a gentle sweetness and savory depth.
5. Add the catfish steaks. Simmer gently until just opaque and the flesh flakes at the edges, 5–7 minutes, skimming as needed.
6. Add the pineapple chunks and sliced okra. Simmer until tender-crisp, 3–4 minutes; the okra should be just soft around the edges.
7. Add the sliced elephant ear stem (bac ha) and tomato wedges. Simmer until the tomatoes just soften and bac ha is juicy but still crisp, 1–2 minutes.
8. Stir in the sliced scallions and turn off the heat. Taste and adjust seasoning with the salt, more fish sauce, or a splash of tamarind liquid (if reserved), aiming for a lively sour-sweet-salty balance.
9. Divide the bean sprouts among serving bowls (for serving). Ladle the hot soup and fish over the sprouts to lightly wilt them. Top with the chopped rice paddy herb and sawtooth herb (for serving). Serve immediately.
