Sinigang Mix Sachet Pork Sinigang Recipe

Filipino pork sinigang is a savory, sour soup with tender pork and vegetables, and a sinigang mix sachet makes its signature tangy broth simple to prepare. This version builds flavor with onion, tomato, fish sauce, and a packet of tamarind-based seasoning, then adds vegetables in stages so they stay pleasantly tender rather than overcooked.

Ingredients

1½ lb (680 g) boneless pork shoulder, cut into 1-inch (2.5 cm) cubes
1 tbsp (15 ml) neutral cooking oil
1 medium yellow onion, about 6 oz (170 g), peeled and cut into wedges
2 medium ripe tomatoes, about 8 oz (225 g), cut into wedges
8 cups (1.9 L) water
1 sinigang mix sachet, about 40 g, or the packet amount recommended for about 8 cups (1.9 L) liquid
1 tbsp (15 ml) fish sauce, plus more to taste
1 medium daikon radish, about 8 oz (225 g), peeled and cut into ½-inch (1.25 cm) half-moons
1 small eggplant, about 8 oz (225 g), cut into 1-inch (2.5 cm) pieces
6 oz (170 g) green beans, trimmed and cut into 2-inch (5 cm) lengths
1 long green chili, such as a finger chili, left whole or slit once lengthwise
4 oz (115 g) kangkong, also called water spinach, cut into 3-inch (7.5 cm) lengths
¼ tsp (1.5 g) fine salt, only if needed after tasting
4 cups (about 600 g) cooked rice, for serving

Instructions

Prepare the ingredients. Cut the pork into evenly sized pieces so they cook at a similar rate. Cut the onion and tomatoes into wedges, prepare the radish, eggplant, and beans, and rinse the kangkong well, especially around the stems. Keep the vegetables separate because they go into the pot at different times. If the pork is wet, pat it dry so it browns more readily.
Brown the pork and soften the aromatics. Heat the oil in a heavy 5- to 6-quart (4.7- to 5.7 L) pot over medium-high heat. Add the pork in a single layer, working in batches if the pot is crowded, and brown it for about 5 minutes, turning the pieces once or twice. It does not need to cook through at this point. Add the onion and tomatoes and cook for 2 minutes, stirring and scraping up browned bits from the bottom.
Simmer the pork. Pour in the water and add the fish sauce. Bring the pot to a boil, then lower the heat so the liquid simmers gently. Cover partially and simmer for 45 minutes, skimming off excess foam if you like. Check that the pork is becoming tender; if the pieces are still firm, continue simmering in 5-minute increments. The pork should reach the USDA FSIS safe minimum internal temperature of 145°F (63°C), checked with a food thermometer, and rest for 3 minutes; simmering it longer until tender is appropriate for this soup.
Season the broth with the sachet. Stir in the sinigang mix until it dissolves. Start with the packet quantity recommended for the amount of liquid in your pot, since sachet sizes and strengths vary. Let the broth simmer for 2 minutes, then taste it. Add a little more mix if you want a sharper sour flavor, but reserve salt until the end because the seasoning and fish sauce both contribute saltiness.
Cook the firm vegetables. Add the daikon and whole green chili. Simmer for 5 minutes, then add the eggplant and green beans. Continue simmering for 7 to 9 minutes, until the radish is just tender and the beans and eggplant are cooked but still hold their shape. Avoid a hard boil, which can break up the vegetables and make the broth cloudy.
Finish and adjust. Add the kangkong and cook for 2 to 3 minutes, just until the leaves have wilted and the stems are tender. Taste the broth again. Add fish sauce for a deeper savory flavor, a small amount of salt if genuinely needed, or a splash of water if the soup is too intense. The finished broth should taste clearly sour and savory, not harshly salty.
Serve hot. Ladle the pork, vegetables, and broth into bowls. Serve with cooked rice on the side or spooned into the soup at the table. Let diners add more rice or fish sauce to suit their taste.

Tips

Use the packet as a starting point. A sachet labeled for a different pot size may make the broth too strong or too mild if added all at once. Check its suggested liquid amount, then add the mix gradually and taste after it dissolves. The soup’s sourness is easy to increase; diluting an over-seasoned pot takes more effort.
Choose pork shoulder for a tender result. Shoulder has enough connective tissue to become soft during a steady simmer. Lean pork loin can be substituted, but it cooks faster and is easier to dry out, so add it later and check it sooner. Keep the pieces similar in size for more even cooking.
Keep vegetables distinct. Radish needs more time than kangkong, so do not add everything together. If using very thin beans or small eggplant pieces, check them early. The pot should simmer gently; vigorous boiling can make delicate vegetables mushy before the pork is ready.
Adjust sourness without masking it. If the broth tastes too sharp, add a little water and taste again, or serve it with extra rice. Avoid adding sugar as a first fix: it can make the soup taste sweet rather than balanced. For a less salty finish, use unsalted water and add fish sauce only after tasting the prepared broth.

Serving Suggestions

Serve sinigang in deep bowls while the broth is hot, with a separate bowl of freshly cooked rice. In many Filipino meals, diners alternate spoonfuls of rice with sour broth, pork, and vegetables; rice can also be added directly to the bowl. A small dish of fish sauce with sliced chili is a familiar optional condiment for people who want extra savory heat, but the soup is satisfying without it.

This pot already includes several vegetables, so keep side dishes simple. Steamed rice is the most useful accompaniment because it balances the pronounced sourness and makes the broth easy to enjoy. If you want another dish on the table, serve a mild vegetable side or sliced fresh cucumber rather than another strongly seasoned stew. Put out a serving spoon so everyone can choose a mix of meat, vegetables, and broth.

Variations

Use another protein: Bone-in pork ribs can replace the shoulder; they may need more simmering time, so cook until tender and check the temperature in a meaty portion without touching bone. For shrimp, use peeled, deveined shrimp and add them near the end, cooking until opaque and firm; avoid prolonged simmering. Fish sinigang is another common style, but choose sturdy fish pieces and cook them gently so they do not fall apart. Fish should reach 145°F (63°C) according to USDA FSIS guidance.

Change the vegetables: Kangkong can be difficult to find outside Filipino or Southeast Asian markets. Substitute baby spinach, adding it at the very end; it wilts faster and has more delicate leaves. Mustard greens work too and bring a stronger, slightly peppery taste. Taro is used in some versions for a soft, thickening texture: add peeled, bite-size pieces with the radish and simmer until tender. Regional and family versions vary, so treat the vegetable list as flexible.

Make it meatless: Leave out the pork and use vegetable broth or water, then add firm tofu and extra mushrooms or vegetables for substance. Check the sachet label for fish-derived ingredients if you need a fully vegetarian soup; some sour soup mixes contain fish or shrimp flavoring. Without pork, the broth will be lighter, so taste and adjust the seasoning at the end.

Use fresh tamarind instead of the sachet: If you have fresh tamarind pulp, simmer it in water and strain the liquid into the soup, adding it gradually to taste. Fresh tamarind varies in sourness and does not provide the same seasoning as a prepared mix, so add fish sauce and salt separately. This takes more time and produces a less standardized broth, but it is a useful option when a sachet is unavailable.

Storage and Reheating

Refrigerate leftover soup within 2 hours of cooking, in a covered container. It keeps for 3 to 4 days in the refrigerator. The vegetables soften as they sit in the sour broth, and kangkong is particularly delicate, but the soup remains suitable for reheating within that window. If you expect leftovers, you can store cooked rice separately so it does not absorb broth while the soup is chilled.

Reheat only the amount you plan to eat in a saucepan over medium heat, stirring occasionally, until steaming throughout and at least 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers. Avoid repeatedly cooling and reheating the entire pot. For longer storage, freeze the cooled soup in meal-size airtight containers for up to 2 to 3 months for best quality. Thaw in the refrigerator and reheat to 165°F (74°C); expect the vegetables to be softer after freezing. Do not leave the soup at room temperature for extended storage.

Frequently Asked Questions

How much sinigang mix should I use?
Use the amount stated on your sachet for roughly 8 cups (1.9 L) of liquid, then taste before adding more. Packet weights and recommended dilutions differ by product, so a fixed number of sachets is less reliable than the label. Stir the mix in completely and give it a couple of minutes to flavor the broth before judging the sourness.

Can I make sinigang mix sachet soup less sour?
Yes. Add water a little at a time, tasting after each addition, and adjust savory seasoning only if needed. You can also serve it with more rice, which softens the sour impression as you eat. Avoid pouring in extra fish sauce to correct sourness, since that adds salt rather than reducing the tang.

Can I make the soup ahead?
Yes. Cook it a day ahead, cool it promptly, and refrigerate it within 2 hours. The flavors mingle as it rests, though the vegetables will soften when reheated. For the best texture, you can cook the pork and broth ahead, refrigerate them, then bring the soup back to a simmer and add the vegetables shortly before serving.

What can I use instead of kangkong?
Baby spinach is the easiest substitute and should be added during the last minute or two, just until wilted. Mustard greens or Swiss chard also work, though they have a stronger flavor and may need a few extra minutes for their stems. The result will not be identical, but the sour broth still pairs well with leafy greens.

Why is my broth too salty?
Sinigang sachets and fish sauce both contain salt, and their strength varies. Dilute the soup with hot water a little at a time, then taste again; add more vegetables or serve with extra rice if you have them. Next time, begin with less fish sauce and avoid adding salt until the sachet has dissolved and the finished broth has been tasted.

Can I use a different cut of pork?
Yes. Pork ribs, pork belly, or another stew-friendly cut can work, although cooking time and richness will vary. Lean loin is less forgiving and should not simmer as long as shoulder. Whatever cut you choose, check a piece with a food thermometer and cook it until safely done; for tender stew-style pork, allow enough gentle simmering for the meat to soften.
