Sinigang Recipe Using Sinigang Mix: Pork Soup Made Easy

Sinigang is a Filipino sour soup, often made with pork and vegetables in a tangy tamarind broth. Using sinigang mix makes the distinctive sour base simple to prepare, while fresh tomatoes, greens, and tender pork give the soup depth and texture.

Ingredients

2 lb (900 g) boneless pork shoulder, cut into 1½-inch (4 cm) pieces
1 tbsp (15 ml) neutral cooking oil
1 large yellow onion, about 7 oz (200 g), peeled and cut into wedges
2 medium ripe tomatoes, about 10 oz (300 g), cut into wedges
8 cups (1.9 L) water
1 packet sinigang seasoning mix, about 1.4 oz (40 g), or the amount recommended on the packet for 8 cups (1.9 L) of broth
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
6 oz (170 g) green beans, trimmed and cut into 2-inch (5 cm) lengths
6 oz (170 g) water spinach, also called kangkong, rinsed and cut into manageable lengths
2 green finger chiles, about ¾ oz (20 g) total, left whole or slit once lengthwise
1 tbsp (15 ml) fish sauce, plus more to taste
¼ tsp (0.5 g) ground black pepper
½ tsp (3 g) fine salt, only if needed after tasting

Instructions

Prepare the ingredients. Cut the pork and vegetables as directed, keeping the greens separate from the firmer vegetables. Rinse the water spinach well, since grit can collect around the stems. If your pork pieces vary in size, trim or cut them so they cook at roughly the same rate.
Soften the aromatics, 3 minutes. Heat the oil in a large, heavy pot over medium heat. Add the onion and tomatoes and cook, stirring occasionally, until the onion begins to soften and the tomatoes start to release their juices. This short step builds a savory base; the tomatoes will continue to break down in the broth.
Add the pork and bring the broth to a simmer, about 7 minutes. Add the pork, water, whole chiles, and black pepper. Raise the heat and bring the pot just to a boil, then reduce the heat to maintain a gentle simmer. Skim off any gray foam that gathers on the surface for a clearer-looking broth. Avoid a hard boil, which can make the meat and vegetables jostle around and the broth evaporate too quickly.
Simmer until the pork is tender, about 65 minutes. Partly cover the pot and cook gently, checking now and then that the liquid is still at a steady simmer. The pork should be easy to pierce with a fork but should still hold its shape. Use a food thermometer to check the largest piece: USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of pork. In this soup, the pork will typically cook well past that minimum as it becomes tender.
Season the broth with the mix, 2 minutes. Stir in the sinigang mix gradually, starting with about three-quarters of the packet if you are unsure how sour or salty your preferred mix is. Stir until dissolved and simmer for 2 minutes so the flavor disperses. You can add the remaining mix after tasting; packets vary in strength and saltiness.
Cook the firm vegetables, 8 minutes. Add the daikon and eggplant. Simmer gently for about 8 minutes, or until the daikon is nearly tender when pierced and the eggplant is soft but not falling apart. If you cut the daikon thicker than directed, give it a few extra minutes before adding the next vegetables.
Add the green beans, 4 minutes. Stir them into the broth and cook for about 4 minutes, until bright and tender-crisp. Add the water spinach and cook for 3 minutes, just until the leaves wilt and the stems soften. Stir in the fish sauce, then taste the broth. Add more seasoning mix for extra sourness, fish sauce for savory depth, or a little salt if the broth needs it. Allow about 3 minutes for this final adjustment and serving setup.
Serve hot. Ladle pork, vegetables, and plenty of broth into bowls. Keep the chiles whole if you want them to flavor the soup without making every spoonful spicy, and let diners decide whether to eat them.

Tips

Let the packet guide you, then taste. Sinigang mixes differ in sourness, salt, and packet size. The recipe starts with a 40 g packet intended for this amount of broth, but check the package directions and add it gradually. Adding the entire packet at once can make a particularly strong mix too salty or sour.
Use a gentle simmer. A rolling boil can break up tender pork and make eggplant collapse before the other vegetables are ready. Keep the surface bubbling lightly and add a splash of hot water if the broth reduces more than you like.
Choose pork shoulder for a forgiving result. Its connective tissue softens during a long simmer and gives the soup a fuller broth. Lean pork loin can be used, but it cooks faster and is easier to overcook; cut it into larger pieces and begin checking it earlier.
Keep the greens fresh-tasting. Add water spinach near the end rather than simmering it with the pork. If using baby spinach instead, add it just before serving because its leaves wilt much faster and have a softer texture.

Serving Suggestions

Serve sinigang hot in individual bowls with steamed white rice. The rice is usually served alongside rather than cooked in the soup, so it stays fluffy and can be spooned into the sour broth a little at a time. Set out extra rice for anyone who wants to balance a particularly tangy or spicy bowl.

For a simple meal, the pork and vegetables make the soup substantial on their own. You can also put fish sauce, sliced fresh chile, and calamansi or lime wedges on the table so diners can adjust their bowls. A squeeze of citrus is optional—the mix already provides the sour flavor—but it can brighten a serving. Keep any extra seasoning separate rather than making the whole pot too salty or hot for the table.

Variations

Use another cut of pork: Pork ribs or country-style ribs work well and add a richer flavor, though cooking time depends on the size and bone. Start checking for tenderness after about an hour and continue simmering as needed. Pork belly is another option for a richer, fattier broth; skim excess fat from the surface if desired.

Swap the vegetables: Water spinach is a familiar sinigang green, but it may be hard to find. Baby spinach is convenient and wilts more quickly, while bok choy gives a firmer stem and a milder flavor. Taro, okra, or sliced radish can also be used; add each according to how long it takes to become tender. Different households and regions use different combinations, so the vegetables are easy to adapt.

Make a seafood version: Replace the pork with firm fish or peeled shrimp, but do not use the pork simmering time. Prepare the broth and vegetables first, then add seafood near the end. Cook fish to 145°F (63°C) as checked with a food thermometer; shrimp should be cooked until opaque and firm. Seafood cooks quickly, so add it only when the vegetables are nearly done.

Adjust the sourness without changing the whole pot: For a sharper broth, add a little extra mix or serve citrus at the table. For a gentler flavor, dilute the soup with a small amount of hot water or unsalted broth. Fresh tamarind pulp can replace some of the mix, but it brings a less uniform sourness and may require more salt; taste as you go.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in shallow, covered containers. Keep the soup refrigerated for 3–4 days. If possible, store rice separately so it does not absorb the broth and turn soft. The vegetables will become more tender as they sit, especially the eggplant and greens, but the soup remains suitable for reheating within that storage window.

To reheat a serving on the stove, warm it gently in a saucepan, stirring occasionally, until steaming throughout. For food safety, reheat leftovers to 165°F (74°C), checked with a food thermometer. In a microwave, cover the bowl loosely, stir partway through, and check several spots for an even temperature. Add a splash of water if the broth has reduced or the soup seems too concentrated.

For longer storage, freeze the cooled soup in airtight, freezer-safe containers, leaving a little room for expansion. It is best used within 2–3 months for quality. Thaw it overnight in the refrigerator when convenient, then reheat to 165°F (74°C). The vegetables may soften further after freezing and thawing, so if you plan to freeze a batch, you can slightly undercook them and finish cooking them during reheating.

Frequently Asked Questions

What is sinigang mix made from?
Sinigang mix is a powdered seasoning designed to make the soup’s sour broth. Many versions use tamarind flavoring and include salt and other seasonings, but ingredients vary by product. Read the packet label if you need to check for a particular ingredient, and taste before adding extra salt.

How much sinigang mix should I use?
Use the amount on the packet for the volume of broth you are making. This recipe uses about 40 g for 8 cups (1.9 L) of water, but brands and packet strengths differ. Start with less if you prefer a mild broth, dissolve it fully, and add more in small amounts until the sourness suits you.

Can I make sinigang without fish sauce?
Yes. Leave it out and season with salt to taste, or use a small amount of soy sauce for savory depth. Soy sauce changes the flavor and darkens the broth, so add it gradually. Check the seasoning mix first, since some packets are already quite salty.

Why is my sinigang too sour or too salty?
The packet may be stronger than expected, or it may be intended for less water. Add a little hot water or unsalted broth, then taste again. If you dilute the soup, you may want a small amount of fish sauce for savory flavor, but avoid adding more salty seasoning until the balance is right.

Can I prepare sinigang ahead?
Yes. You can cook the pork and broth a day ahead, cool and refrigerate them promptly, then reheat the soup and cook the vegetables shortly before serving for a fresher texture. If the vegetables are already in the soup, reheat gently because they will soften more. Refrigerate cooked soup within 2 hours and use it within 3–4 days.

Can I use a different sinigang flavor packet?
Yes. Mixes flavored with different souring ingredients or seasonings can work, but they may taste different from a tamarind-style version. Follow the packet’s suggested dilution, add it gradually, and adjust the broth only after tasting. The pork and vegetable method stays the same, though some seafood or fish versions need much less cooking time.
