Sinigang na Baboy Recipe with Knorr and Fresh Vegetables

Sinigang na baboy is a Filipino pork-and-vegetable soup with a savory, distinctly sour broth, commonly served hot with rice. This version uses Knorr Sinigang sa Sampalok mix for a dependable tamarind flavor, balanced with fresh tomatoes, radish, long beans, eggplant, and leafy greens; households adjust the sourness and vegetables 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 as needed
1 medium yellow onion, about 6 oz (170 g), peeled and quartered
2 medium ripe tomatoes, about 10 oz (280 g), quartered
1 lb (450 g) daikon radish, peeled and sliced into ½-inch (1 cm) rounds
1 packet (about 1.4 oz/40 g) Knorr Sinigang sa Sampalok mix, or the amount directed on the packet
8 oz (225 g) long beans, cut into 2-inch (5 cm) lengths
1 medium Asian eggplant, about 8 oz (225 g), cut into 1-inch (2.5 cm) pieces
2 cups (about 60 g) fresh kangkong (water spinach), cut into manageable lengths, or 3 cups (90 g) baby spinach
1–2 tablespoons (15–30 ml) fish sauce, plus more to taste
1 small green chile, such as a long green finger chile, optional
Steamed rice, for serving

Instructions

Start the broth. Put the pork and water in a large, heavy pot. Bring to a gentle boil over medium-high heat, skimming off foam as it rises. Add the onion and tomatoes, then lower the heat to maintain a steady simmer. Avoid a hard boil, which can make the broth cloudy and the pork tougher.
Simmer until tender. Partially cover the pot and simmer for 50–60 minutes, checking occasionally and skimming excess fat if desired. Turn the pork pieces once or twice and add a little hot water if the meat becomes exposed. The pieces should be easy to pierce with a fork, but not falling apart.
Check pork temperature. Use a food thermometer in the thickest piece, avoiding the bone. The USDA FSIS safe minimum for whole cuts of pork is 145°F (63°C) followed by a 3-minute rest; for this soup, continue simmering until the pork is also fork-tender. If it has not reached the safe minimum, cook longer and check again.
Season the sour broth. Stir in the Knorr Sinigang mix, starting with the packet amount or following its package directions. Add the radish and simmer for 8–10 minutes, until it is nearly tender. Taste the broth; add more mix if you prefer it more sour, but add it gradually because packet strengths vary.
Cook the remaining vegetables. Add the long beans, eggplant, and optional chile. Simmer for 5–7 minutes, until the vegetables are tender but still hold their shape. Stir in the fish sauce, beginning with 1 tablespoon (15 ml), then adjust to taste.
Finish and serve. Add the kangkong and simmer for 1–2 minutes, just until wilted. If using baby spinach, turn off the heat before stirring it in; residual heat will wilt it. Taste once more for sourness and salt, then serve hot with steamed rice.

Tips

Choose the pork cut for the texture you want. Bone-in shoulder gives the broth body and becomes tender with a long simmer. Pork ribs also work; lean pork loin cooks faster but can turn dry, so add it later and avoid overcooking.
Adjust the seasoning in stages. Knorr packet sizes and salt levels can differ. Start with the package guidance, taste after the radish softens, and add mix or fish sauce a little at a time. If the soup gets too sour or salty, dilute it with hot water and recheck the flavor.
Keep the vegetables intact. Cut pieces to similar sizes and add them in stages rather than all at once. Radish needs more time than greens; adding leafy vegetables at the end keeps them from going dull and mushy.
Use a sensible substitute for kangkong. Water spinach is sold at many Asian grocers but may be hard to find. Baby spinach is convenient and mild, though it softens more quickly and has a less distinctive texture; bok choy is another option, added with the eggplant.

Serving Suggestions

Serve sinigang in deep bowls while the broth is hot, with a separate bowl of steamed white rice for soaking up the sour soup. Put extra fish sauce and sliced fresh chile on the table so each person can season their own portion. The soup is substantial enough to be the main course; a simple side of sliced cucumber or another fresh vegetable offers a crisp contrast without competing with the broth.

Variations

For a different pork texture, use meaty ribs or pork belly in place of some or all of the shoulder. Belly makes the broth richer, so skim fat before serving if you prefer a lighter soup. Add taro (gabi) with the radish for a thicker, softer texture, or use okra in place of some of the long beans. Some cooks include green pepper or extra tomato, while others favor a sharper broth; these are common household adjustments rather than a single fixed formula.

If you cannot find the Knorr mix, use another tamarind-based sinigang seasoning packet according to its directions. For a from-scratch sour broth, simmer tamarind pulp or fresh tamarind pods in water, strain out the seeds and fibers, then add the liquid gradually to taste and season with salt or fish sauce. The flavor and strength vary with the fruit, so it will not match a packet exactly. Unripe guava or green mango can also sour the broth, but each gives it a different aroma and taste.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking, in shallow, covered containers. Store for 3–4 days at 40°F (4°C) or below. For longer storage, freeze in airtight portions; use within about 2–3 months for best quality, knowing the eggplant and leafy greens may soften after thawing.

Reheat only the amount you plan to eat, on the stovetop over medium heat, stirring occasionally until the soup reaches 165°F (74°C) throughout; check with a food thermometer. Bring it to a gentle simmer rather than boiling it hard, which can break up the vegetables. Add a splash of water if the broth has concentrated. Do not leave cooked soup at room temperature for more than 2 hours, or more than 1 hour when the temperature is above 90°F (32°C).

Frequently Asked Questions

Can I use a different Knorr Sinigang packet size?
Yes. Follow the packet’s directions as a starting point, since product sizes and recommendations can vary by market. Taste the broth before adding the full amount if you are unsure; you can stir in more seasoning, but it is harder to correct an overly salty soup.

Why is my sinigang not sour enough?
Add more sinigang mix in small increments, simmer briefly, and taste again. If using tamarind instead, add strained tamarind liquid gradually. Tomatoes add brightness but are not a substitute for tamarind’s characteristic sourness.

Can I make it ahead?
Yes. The pork and broth can be cooked ahead and refrigerated within 2 hours. For the best vegetable texture, reheat the soup to 165°F (74°C) and cook freshly cut vegetables in it until tender. If the vegetables are already in the soup, reheat gently and expect them to be softer.

Can I make sinigang without fish sauce?
Yes. Leave it out and season with salt, adding a little at a time. Fish sauce contributes salty, savory depth, so the finished broth will taste somewhat different; a small amount of soy sauce can add savoriness but also changes the flavor.

What should I do if I cannot find daikon or long beans?
Use turnip in place of daikon, keeping in mind its flavor is sharper, or use green beans in place of long beans. Cut substitutes into similar-sized pieces and add them when they need enough time to become tender without turning mushy.
