01 - Bring 6 cups water to a boil in a large stockpot. Add pork chunks, skimming off any scum that rises to the surface for a clearer broth.
02 - Add quartered tomatoes and onions to the pot. Simmer for 20 minutes until pork begins to tenderize and flavors meld together.
03 - Stir in sliced daikon radish and continue cooking for 10 minutes until the radish becomes tender but still retains some crunch.
04 - Add eggplant slices, string beans, and green chili peppers. Simmer for 5 minutes until vegetables are partially cooked.
05 - Mix in the tamarind soup base, ensuring it dissolves completely. If using fresh tamarind pulp, mash and strain into the soup for smooth texture.
06 - Season with fish sauce, salt, and black pepper. Taste and adjust seasoning according to preference, balancing sour and savory notes.
07 - Add spinach or kangkong leaves and simmer for 2–3 minutes until just wilted. Avoid overcooking to maintain vibrant color and texture.
08 - Ladle hot soup into bowls and serve immediately with steamed white rice for a complete Filipino comfort meal.
