Filipinos love the savory sour flavor. And this all-time favorite Filipino dish is an evidence of that. The pucker from this soup comes from tamarind.
Filipinos love using sour fruits in their dishes. Wherever in the country you may be, there’ll always be a fruit you can use for this recipe. Among the common options are batwan, calamansi, bilimbi (kamias) , green mangoes, and in the case of this Sinigang dish, tamarind (sampalok).
In a large pot over medium heat, place your pork ribs and cover with water. Add onions and tomatoes to the pot. Bring to a boil, then lower the heat and let it simmer gently for about 1 hour, or until the pork is tender and flavorful. Skim off any scum that rises to the surface for a clearer broth.
In another pot, boil the unripe tamarind in 1 1/3 cups of water for about 5 to 10 minutes. Once it’s done, mash it, then strain the juice and set aside.
Once the pork is tender, stir in the tamarind juice to give the soup its signature tangy flavor. For more flavor, submerge the tamarind in a strainer into the soup. Season with fish sauce to enhance the umami taste, then let it simmer for a few more minutes.
Add the firmer vegetables first: sliced radish, string beans, okra, and eggplant. Cook for 2 to 3 minutes until they start to soften but still hold their shape.
Toss in fresh water spinach (kangkong) and green chilies. Season the soup with salt and pepper. Simmer for just another minute—you want the greens to stay bright and tender, not overcooked.
Ladle the sinigang into bowls, making sure each serving has tender pork and plenty of vegetables. Serve with steamed rice on the side for a comforting, tangy, and heartwarming meal that’s perfect any day.
The signature tang of Sinigang traditionally comes from tamarind, but you can adjust the sourness by gradually adding tamarind paste or powder to your simmering broth. For the best flavor profile, balance the acidity with a few splashes of fish sauce (patis), which adds a deep umami layer that rounds out the pucker. Always taste your broth after adding the tamarind to ensure it hits your preferred level of tartness before adding the greens.
The secret to perfect Sinigang texture is staggered cooking. Add firmer vegetables like radish, okra, and eggplant first, allowing them 2–3 minutes to soften. Only add delicate leafy greens, such as kangkong (water spinach), in the final minute of cooking, then immediately remove the pot from the heat. This method ensures your vegetables stay vibrant and hold their shape rather than turning into a gray, soft mess.
If tamarind is unavailable, you can achieve a similar sour profile using calamansi juice, lemon, or green mangoes. In a pinch, some cooks use “sinigang mix” packets, but fresh acidic fruits provide a more complex brightness. Simply stir in your citrus juice or mashed sour fruit at the same stage you would add the tamarind paste, adjusting the quantity to taste.
To prevent a cloudy or muddy soup, always skim the scum (the gray foam) that rises to the surface during the initial boil of the pork ribs. Additionally, simmer the pork gently over low-medium heat rather than a rolling boil, which prevents the fat and proteins from emulsifying into the liquid. This technical step results in a clean, savory broth that highlights the colors of the fresh vegetables.
Sinigang stores well in the refrigerator for up to 3 days in an airtight container; in fact, the flavors often deepen overnight. When reheating, do so over medium heat on the stove and avoid over-boiling to prevent the vegetables from disintegrating. If you plan on freezing the dish, it is best to freeze the broth and meat only, then add fresh vegetables upon reheating to maintain their crisp texture.
