Sinigang Recipe with Knorr: Pork and Vegetables

Sinigang is a Filipino sour soup, often made with pork, vegetables, and a tart tamarind broth. This version uses Knorr Sinigang sa Sampalok mix for a convenient, consistent sour base, with pork shoulder simmered until tender and vegetables added in stages so they keep their shape.

Ingredients

2 lb (900 g) boneless pork shoulder, cut into roughly 1½-inch (4 cm) cubes
8 cups (1.9 L) water
1 medium yellow onion, about 5 oz (150 g), peeled and cut into wedges
2 medium tomatoes, about 10 oz (300 g), cut into wedges
1 packet (44 g) Knorr Sinigang sa Sampalok mix
1 tablespoon (15 ml) fish sauce, plus more to taste
1 medium daikon radish, about 12 oz (350 g), peeled and cut into ½-inch (1 cm) half-moons
1 small Asian eggplant, about 9 oz (250 g), cut into 1-inch (2.5 cm) pieces
1 cup (125 g) trimmed green beans, cut into 2-inch (5 cm) lengths
4 packed cups (120 g) water spinach, also called kangkong, tough lower stems removed and leaves and tender stems cut into manageable lengths
2 long green chilies, whole or slit once, optional
¼ teaspoon (1 g) ground black pepper, or to taste

Instructions

Prepare the ingredients. Cut the pork into similar-sized pieces so they cook evenly. Rinse and cut the vegetables, keeping the radish, eggplant, beans, and water spinach separate because they go into the pot at different times. Keep the water spinach leaves and tender stems together; discard any particularly tough stem ends.
Start the broth. Put the water, onion, and tomatoes in a large, heavy pot or Dutch oven. Set it over medium-high heat and bring the water to a boil, which should take about 5 minutes. Add the pork and fish sauce. When the liquid returns to a gentle boil, lower the heat until it simmers steadily. Skim off any gray foam that gathers on top during the first few minutes for a clearer-looking broth.
Simmer the pork until tender. Partially cover the pot and simmer for about 55 minutes, stirring occasionally and adjusting the heat to prevent a hard boil. A gentle simmer helps the pork become tender without making the broth cloudy or reducing it too quickly. If the meat is not tender after 55 minutes, continue simmering and check again in 10-minute intervals; tougher or larger pieces may need longer.
Check the pork and season the broth. Use a food thermometer inserted into the center of a large piece of pork. The USDA FSIS safe minimum for whole cuts of pork is 145°F (63°C), followed by a 3-minute rest; make sure the pieces meet that minimum and remain hot in the broth for at least 3 minutes. Pork shoulder is generally cooked beyond the minimum here so it turns tender. Stir in the Knorr mix and black pepper until the powder dissolves. Taste the broth before adding extra salt: the seasoning mix and fish sauce already contribute saltiness.
Cook the firm vegetables first. Add the daikon and chilies, if using, and simmer for 8 minutes. The radish should begin to soften but still hold its shape. Add the eggplant and green beans and simmer for 5 minutes more, checking that the vegetables are becoming tender without turning mushy.
Finish with the greens and adjust. Stir in the water spinach and simmer for about 2 minutes, just until the leaves wilt and the tender stems soften. Taste the soup. Add a little more fish sauce for savory depth, or a small amount of additional tamarind mix if you prefer a sharper, more sour broth. Serve hot while the greens are still bright.

Tips

Use the packet as a starting point. Knorr packet sizes and directions can vary by market. This recipe is calibrated for a 44 g packet; if yours is a different size, check its serving guidance and add it gradually, tasting before using the full amount. You can always add more mix, but it is difficult to correct a broth that has become too sour or salty.
Keep the broth at a gentle simmer. A rolling boil can break up the pork and vegetables and evaporate liquid quickly. If the pot becomes too concentrated, add hot water a little at a time, then taste and adjust the seasoning again.
Choose vegetables that suit the pot. Water spinach is traditional in many versions, but it can be hard to find. Substitute baby spinach for a softer, more delicate finish, or use bok choy for a sturdier green. These swaps change the texture and flavor slightly, so add them at the end and cook only until tender.
Season in small additions. The packet is already a sour, seasoned base. Let it dissolve fully before deciding whether the soup needs more fish sauce or sour mix, and avoid adding salt automatically. If the broth tastes too intense, dilute it with a little hot water rather than trying to mask it with sugar.

Serving Suggestions

Serve sinigang in deep bowls with plenty of broth, a few pieces of pork, and a mix of vegetables in each serving. Steamed white rice is the classic partner: serve it alongside, or spoon some into the bowl so it absorbs the sour broth. Keep extra rice on the table for anyone who prefers a milder balance between soup and rice.

For a simple condiment, offer fish sauce with sliced fresh chili on the side, so each person can season their own portion. The soup is filling as a main meal, but it also works as part of a Filipino-style spread with rice and a plainly cooked side dish. Serve it soon after the greens go in; they are at their best before they lose their color and texture.

Variations

Sinigang has many regional and family versions, and the protein and souring ingredient can change. This recipe uses pork and a packaged tamarind seasoning for ease, rather than claiming to be the only way to make the dish. For a richer pork version, use bone-in shoulder or ribs; allow extra simmering time until the meat is tender, and top up the water if needed. Pork belly also works, though it makes a richer broth.

To make shrimp sinigang, use peeled or shell-on shrimp and add them near the end, simmering only until they are opaque and reach 145°F (63°C) as checked with a food thermometer. For fish sinigang, add sturdy fish pieces toward the end and cook until they reach 145°F (63°C). These quick-cooking proteins do not need the long pork simmer, so prepare the broth and vegetables first, then cook the seafood just before serving.

If you cannot find a Knorr packet, use another tamarind-based sinigang mix according to its package directions; the salt and sourness may differ. Tamarind concentrate or a homemade tamarind broth can also provide tartness, but it will not have the same seasoning blend, so add it gradually and season with fish sauce to taste. For a different sour profile, some cooks use other souring fruits, such as green mango or guava, where available. Those choices make a noticeably different broth rather than a direct one-for-one substitute.

Vegetables can be adjusted to what is available. Add taro early enough to cook until tender, or include sliced okra near the end if you like its soft, slightly thickening texture. If using tender greens other than water spinach, add them last. Keep the overall amount of vegetables similar so they do not crowd the pot and absorb too much of the broth.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours in shallow, covered containers. Store the broth, pork, and vegetables together or separately, and use refrigerated leftovers within 3–4 days. The vegetables will soften as they sit in the sour broth, especially the greens, so separating them before storage helps preserve their texture if you expect leftovers.

For longer storage, freeze cooled soup in airtight, freezer-safe containers for up to about 2–3 months for best quality. Leave a little room at the top for expansion. Thaw it in the refrigerator overnight, or reheat it from frozen over low heat with a splash of water; stir gently as it warms so the pork and vegetables do not break apart.

Reheat only the amount you plan to eat, on the stovetop over medium-low heat or in the microwave in a covered, microwave-safe bowl. Stir occasionally and heat leftovers to 165°F (74°C), checking with a food thermometer. Bring the broth to a gentle simmer, not a prolonged boil. If reheating changes the balance, add a little water for a concentrated broth or a small amount of fish sauce for seasoning; taste before adding more sour mix.

Frequently Asked Questions

What does Knorr Sinigang mix taste like?

It gives the broth a distinctly tart, tamarind-style flavor along with seasoning. The exact balance can vary between packet sizes and markets. Start with the amount in the recipe, taste after it dissolves, and add more only if you want a stronger sourness.

Can I make sinigang ahead of time?

Yes. You can simmer the pork and prepare the broth a day ahead, then refrigerate it promptly. For the freshest vegetable texture, reheat the broth until steaming and add the vegetables shortly before serving. If everything has already been cooked together, the soup is still fine to reheat, but the greens and eggplant will be softer.

How do I make the broth more sour or less sour?

For more sourness, stir in a little additional sinigang mix, or add tamarind concentrate gradually if you are using it. For a less intense broth, add hot water in small amounts and taste again. A large addition of water also dilutes the seasoning, so you may need a small amount of fish sauce to restore its savory balance.

Why is my pork still tough?

Pork shoulder becomes tender through slow simmering, and the time depends on the size of the pieces and the cut. Keep the pot at a gentle simmer and give the pork more time, checking every 10 minutes. If the broth is reducing too much before the meat softens, add hot water. Do not rely on the clock alone to judge tenderness.

Can I use a different cut of pork?

Yes. Pork ribs, pork belly, or another stew-friendly cut can work, but each has a different amount of fat and may need a different cooking time. Cut boneless meat into similar-sized pieces; if using bone-in pieces, allow extra time for them to become tender and check that there is enough broth to cover most of the meat.

What can I use instead of kangkong?

Baby spinach is easy to find and wilts quickly, though it is more delicate and has a milder flavor. Bok choy is a sturdier option; add its stems before the leaves so both finish tender. Water spinach is sold as kangkong in many Asian grocery stores, often in the produce section.
