Pork Sinigang sa Gabi: A Tangy Filipino Soup

Pork sinigang sa gabi is a Filipino sour soup made with tender pork, taro root, vegetables, and a tart broth, often flavored with tamarind. Gabi (taro) softens as it cooks and helps give the soup a fuller, gently thickened texture; families vary the vegetables and souring ingredients to taste.

Ingredients

2 lb (900 g) bone-in pork shoulder, cut into 1½-inch (4 cm) pieces
10 cups (2.4 L) water, plus more if needed
1 medium yellow onion, about 6 oz (170 g), peeled and quartered
2 medium tomatoes, about 10 oz (280 g), cut into wedges
1 tbsp (15 ml) fish sauce, plus more to taste
8 oz (225 g) fresh gabi (taro root), peeled and cut into 1-inch (2.5 cm) chunks
1 packet (about 1.4 oz/40 g) sinigang sa sampalok (tamarind soup) seasoning mix
1 small daikon radish, about 8 oz (225 g), peeled and cut into ½-inch (1 cm) half-moons
1 long green chili, such as siling haba, left whole
8 oz (225 g) green beans, trimmed and cut into 2-inch (5 cm) lengths
1 small eggplant, about 8 oz (225 g), cut into 1-inch (2.5 cm) chunks
6 oz (170 g) water spinach (kangkong), cut into 3-inch (7.5 cm) lengths, or baby spinach
¼ tsp (1 g) ground black pepper
Cooked rice, for serving

Instructions

Prepare the ingredients. Peel the gabi with a vegetable peeler or knife and cut it into chunks. If handling taro irritates your skin, wear gloves and avoid touching your eyes. Cut the pork and vegetables as listed. Keep the water spinach stems and leaves together; they cook quickly and go in near the end.
Start the broth. Put the pork, water, onion, tomatoes, and fish sauce in a large, heavy pot. Bring to a boil over medium-high heat, skimming off foam that rises to the surface. Lower the heat to maintain a gentle simmer, partially cover, and cook for 45 minutes. A hard boil can make the broth cloudy and the pork fibers tougher.
Simmer the gabi. Add the gabi and daikon. Simmer uncovered for 20 minutes, or until the pork is very tender and the gabi is soft enough to pierce easily with a fork. Check occasionally and add a little hot water if the broth has reduced more than you like. For food safety, check the thickest pork piece with a food thermometer: whole cuts of pork must reach the USDA FSIS safe minimum of 145°F (63°C), followed by a 3-minute rest. The longer simmer here should make shoulder tender as well.
Season the soup. Stir in the sinigang seasoning mix and add the whole green chili. Start with one packet, then taste the broth before adding anything else; packet strengths and sourness vary. Simmer for 3 minutes so the flavor disperses. Adjust with more fish sauce for savoriness or a small amount of water if it tastes too concentrated.
Add the quick-cooking vegetables. Add the green beans and eggplant and simmer for 5 minutes, until just tender. Stir in the water spinach and cook for 2 minutes, until wilted. Add black pepper, taste again, and serve hot. Remove the whole chili if you prefer a milder soup.

Tips

Choose a cut with some connective tissue. Pork shoulder or country-style ribs make a flavorful broth and soften during a long simmer. Lean pork loin cooks faster but can become dry; if using it, add it later and check doneness with a thermometer.
Handle fresh gabi carefully. Raw taro can irritate skin and should not be eaten raw. Peel it, cook it fully until tender, and wash your hands and tools after handling. Frozen peeled taro is a convenient alternative; add it straight from frozen and allow extra time to soften.
Control the sourness. Tamarind soup mix is widely available in Filipino and Asian groceries. If unavailable, use about ½ cup (120 ml) strained tamarind concentrate, adding it gradually and tasting. The broth may be less salty, so adjust fish sauce as needed. Lime or lemon gives a sharper, different flavor rather than the rounded sourness of tamarind.
Keep the vegetables distinct. Add firm roots before tender greens, and avoid prolonged boiling once the greens go in. This keeps the vegetables from becoming limp while the pork finishes cooking.

Serving Suggestions

Ladle the pork, gabi, and vegetables into deep bowls with plenty of broth. Serve with steamed white rice on the side or spoon a little broth over the rice. Put extra fish sauce with sliced chili on the table for diners who want more salty heat. A simple plate of fresh fruit or sliced tomatoes can round out the meal without competing with the sour soup.

Variations

Swap the pork shoulder for pork ribs; they may need a little longer to become tender, so judge by texture rather than the clock. For a lighter version, use pork tenderloin, add it after the roots have simmered, and cook only until a thermometer reads 145°F (63°C), then rest it for 3 minutes before serving. Replace daikon with radish or omit it, and use bok choy or baby spinach if water spinach is hard to find. Sinigang is also made with other proteins and souring agents, but those changes create a different version of the soup.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking in a covered, shallow container. They keep for 3–4 days in the refrigerator. The gabi may soften further and thicken the broth as it sits; stir in a little water when reheating if needed. Reheat only the portion you plan to eat on the stove or in the microwave until it reaches 165°F (74°C), checking with a food thermometer. For longer storage, freeze in airtight containers for up to 2–3 months for best quality; thaw overnight in the refrigerator and reheat to 165°F (74°C). Avoid leaving the soup at room temperature to cool for an extended period.

Frequently Asked Questions

What does gabi do in sinigang?
Gabi is taro root. It turns tender and releases some starch as it cooks, giving the broth a slightly thicker, more substantial feel. It does not replace the souring ingredient.

Can I use fresh tamarind instead of seasoning mix?
Yes. Simmer tamarind pods in water until softened, mash them, and strain the liquid to remove seeds and fibers. Add the strained liquid gradually, tasting as you go; add fish sauce and salt as needed because the seasoning packet also contains salt and other flavorings.

Can I make sinigang sa gabi without pork?
Yes. Use vegetable broth and a firm plant-based protein, or make a vegetable-only soup with extra gabi and green beans. Cooking times will differ, and the broth will not have the same richness as pork broth. Check packaged ingredients if you need to avoid fish sauce or meat-derived seasonings.

Why is my sinigang broth too sour or salty?
Seasoning mixes vary, and adding a whole packet at once can make a small pot overly intense. Dilute a too-sour or salty broth with hot water or unsalted stock, then taste again. Add cooked rice to each bowl rather than using more seasoning to balance it.

Can I make it ahead?
Yes. The soup can be cooked a day ahead and refrigerated promptly. Reheat it to 165°F (74°C), then add a splash of water if the broth has thickened. If you want the greens bright and less soft, cook them fresh and stir them into the reheated soup just before serving.
