Sinigang Recipe: Pork Ingredients, Steps, and Tips

Pork sinigang is a Filipino sour soup made with tender pork, tamarind broth, and vegetables such as daikon, eggplant, and greens. Its balance of savory pork and bright, adjustable sourness makes it a comforting meal served hot with rice; ingredients and souring methods vary by region and household.

This version uses unsweetened tamarind concentrate for a clear, tangy broth and pork shoulder for a tender, full-bodied result. Add the vegetables in stages so they cook through without turning mushy, and taste the broth before serving to fine-tune its sourness and salt.

Ingredients

2 lb (900 g) boneless pork shoulder, cut into 1½-inch (4 cm) pieces
1 tbsp (15 ml) neutral oil
1 medium yellow onion, about 5 oz (150 g), peeled and cut into wedges
4 garlic cloves, about ½ oz (12 g), finely chopped
2 medium ripe tomatoes, about 10½ oz (300 g), cut into wedges
2 tbsp (30 ml) fish sauce, plus more to taste
10 cups (2.4 L) water
⅓ cup (80 ml) unsweetened tamarind concentrate, preferably pure tamarind without added sugar
8 oz (225 g) daikon radish, peeled and cut into ½-inch (1 cm) half-moons
1 medium Asian eggplant, about 9 oz (250 g), cut into 1-inch (2.5 cm) pieces
8 oz (225 g) green beans, trimmed and cut into 2-inch (5 cm) lengths
6 oz (170 g) water spinach (kangkong), thick stems separated from leaves and cut into manageable lengths
2 Thai bird’s-eye chilies, about ⅓ oz (10 g), left whole or lightly slit, optional
½ tsp (1 g) freshly ground black pepper
1 tsp (6 g) kosher salt, or to taste

Instructions

Prepare the vegetables and pork. Cut the pork into similar-sized pieces so they become tender at roughly the same time. Cut the onion and tomatoes into wedges, chop the garlic, and prepare the radish, eggplant, beans, and water spinach. Keep the water spinach leaves separate from the thicker stems. This prep takes about 25 minutes, including trimming and arranging the ingredients.
Start the savory base. Warm the oil in a large, heavy pot or Dutch oven over medium heat. Add the onion and cook for 3 minutes, stirring now and then, until it begins to soften. Add the garlic and cook for about 30 seconds, just until fragrant. Stir in the pork and cook for 3 minutes, turning the pieces so their surfaces lose their raw appearance. They do not need to brown deeply.
Simmer the pork. Add the tomatoes, fish sauce, pepper, and water. Bring the pot to a boil, which usually takes about 8 minutes. Skim off excess foam from the surface, then lower the heat to maintain a gentle simmer. Partly cover the pot and simmer for 75 minutes, stirring occasionally. Keep the liquid at a quiet bubble rather than a hard boil; vigorous boiling can make the broth cloudy and cause the meat to break apart before it is tender.
Check tenderness and safe temperature. After the simmer, pierce a larger piece of pork with a fork. It should be tender but still hold its shape; if it feels firm, simmer for another 10 minutes and check again. Use a food thermometer to check a thick piece. USDA FSIS gives 145°F (63°C) followed by a 3-minute rest as the safe minimum for whole cuts of pork; the longer simmer here is intended to make shoulder tender. Keep the pork in the hot broth for at least 3 minutes before serving.
Add the souring ingredient and firm vegetables. Stir in the tamarind concentrate, daikon, eggplant, green beans, and whole chilies, if using. Bring the soup back to a gentle simmer and cook uncovered for 12–15 minutes, until the radish is tender when pierced and the beans are cooked but not limp. Tamarind concentrates differ in strength, so begin with ⅓ cup and adjust later rather than adding a large extra amount at once.
Finish with greens and season. Add the water spinach stems and cook for 1 minute, then add the leaves and cook for about 1 minute more, just until wilted. Taste the broth. Add salt or fish sauce for savoriness, or another small splash of tamarind concentrate for more sourness. If the broth tastes too sharp, add a little hot water and taste again. Let the pork stand in the broth for 3 minutes, then serve hot.

Tips

Choose tamarind by strength, not just volume. Pure tamarind concentrate can range from gently tart to very intense. Stir it in gradually and taste after the vegetables cook. If you cannot find it, use one packet of sinigang soup base, following its package amount for about 10 cups (2.4 L) of broth. The packet is convenient and often saltier, with a more standardized flavor, so reduce added salt and taste before seasoning.
Keep the simmer gentle. A rolling boil can cloud the broth and rough up the pork. A few small bubbles breaking the surface are enough. If the pot reduces more than you like, add hot water; cold water can interrupt the simmer and slow cooking.
Cook vegetables according to texture. Daikon needs more time than leafy greens, so add it with the eggplant and beans, not at the beginning. If you prefer very soft vegetables, add a few minutes; for vegetables that keep their shape, check them early and stop cooking as soon as they are tender.
Adjust the final bowl, not just the pot. Fish sauce, tamarind, and soup-base products vary in salt and acidity. Make small additions, stir, and taste before adding more. Whole chilies add a mild aroma if left intact; slit them only if you want more heat in the broth.

Serving Suggestions

Serve pork sinigang hot in deep bowls, making sure each portion gets pork, broth, and several kinds of vegetables. Put freshly cooked white rice on the side or in a separate bowl. Diners can spoon the sour broth over rice as they eat; serving rice separately also keeps it from soaking up all the broth before the meal begins.

Offer extra fish sauce and sliced fresh chilies at the table for people who want a saltier or hotter bowl. A small dish of fish sauce with a squeeze of calamansi or lime can be a useful condiment, but it is optional: the soup should already taste pleasantly sour and savory on its own. Since sinigang is a complete soup with pork and vegetables, a simple side of rice is usually enough.

Variations

Use another pork cut. Bone-in pork ribs can replace shoulder and add a richer broth, but allow extra simmering time and check for tenderness rather than relying only on the clock. Pork belly also works for a richer, fattier soup. Trim excess fat if you prefer a lighter-tasting broth, and skim the surface during cooking.

Swap the vegetables. Taro, okra, bok choy, or sliced radish can be used according to availability and preference. Taro takes longer to soften, so add it earlier than the greens. Bok choy cooks quickly and is best added near the end. Traditional water spinach can be difficult to find; regular spinach is a practical substitute, though it is more delicate and has a softer texture. Add it right before serving.

Change the souring method. Tamarind is a familiar choice, but some cooks use green mango, calamansi, guava, or other souring ingredients. Each gives the broth a different aroma and level of tartness. Start with a modest quantity, simmer briefly, and adjust by taste. A packaged sinigang mix is another practical option when fresh or concentrated tamarind is unavailable.

Make it more or less spicy. Leave the chilies out for a mild family-style pot, or serve sliced chilies separately. For a little warmth without dominating the sour broth, slit one chili and remove it once the soup reaches the desired heat. The amount of chili needed varies widely with its size and strength.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking, ideally in shallow, covered containers. Keep the soup refrigerated for 3–4 days. The broth may taste even more rounded after resting, but the vegetables will soften as they sit. For the best texture, store the soup and rice separately and avoid leaving a large pot on the counter to cool for an extended period.

Reheat only the portion you plan to eat, either in a saucepan over medium heat or in a microwave-safe container, stirring as needed so it warms evenly. Reheat leftovers to 165°F (74°C), checking with a food thermometer. Bring the soup to a gentle simmer, but do not boil it for a long time because the pork and vegetables can become overly soft. If the broth has thickened or concentrated in the refrigerator, add a splash of water and taste for seasoning. Freeze portions in airtight freezer-safe containers for up to 2–3 months for best quality; thaw in the refrigerator before reheating.

Frequently Asked Questions

What cut of pork is best for sinigang?

Boneless pork shoulder is a dependable choice because it becomes tender during a long, gentle simmer and gives the broth a savory character. Pork ribs and pork belly are also common options, with ribs adding a deeper broth and belly making it richer. Whichever cut you choose, cut it into pieces of similar size and simmer until tender.

Can I make pork sinigang without tamarind?

Yes. A sinigang soup-base packet is the simplest substitute, and green mango or another tart fruit can provide a different kind of sourness. Follow package directions if using a mix, and remember that many mixes contain salt. Add any souring ingredient gradually and taste the broth, since the level of acidity varies.

Why is my sinigang broth not sour enough?

The tamarind may be mild, or the broth may need more concentrate. Stir in a teaspoon or two, simmer for a minute, and taste again before adding more. If you used a packet, check its directions before adding extra; a little fish sauce can improve savory balance, but it will not make the broth more sour.

Can I prepare sinigang ahead of time?

You can cook the pork and broth ahead, refrigerate them promptly, and reheat them when needed. For firmer vegetables, add them during reheating rather than cooking them fully in advance. If all the vegetables are already in the soup, reheat gently and expect them to be softer than when freshly cooked.

Can I use frozen vegetables or water spinach substitutes?

Frozen green beans can work if thawed and drained, though they may soften faster than fresh beans. If water spinach is unavailable, use spinach, bok choy, or another tender leafy green. Add delicate greens at the end and cook only until wilted so they do not lose their texture in the hot broth.
