Sinigang na Baboy With Sinigang Mix

Sinigang na baboy is a Filipino pork-and-vegetable soup known for its savory, pleasantly sour broth, here made convenient with packaged sinigang mix. Pork ribs simmer until tender, then vegetables are added in stages so they stay flavorful without turning mushy. The mix provides the tart base, while tomatoes, fish sauce, and fresh vegetables round out the pot.

Ingredients

2 lb (900 g) bone-in pork spare ribs or pork shoulder, cut into 2-inch (5 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), cut into wedges
1 tablespoon (15 ml) fish sauce, plus more to taste
1 packet sinigang soup mix, about 1.4 oz (40 g), or the amount specified on the packet for 8 cups (1.9 L) broth
1 medium daikon radish (about 8 oz/225 g), peeled and cut into ½-inch (1.25 cm) rounds
1 small eggplant (about 8 oz/225 g), cut into 1-inch (2.5 cm) pieces
8 oz (225 g) long beans, cut into 2-inch (5 cm) lengths
2 cups (about 100 g) water spinach (kangkong), tough stems trimmed, or baby spinach as a substitute
1 small green chili, such as a long green finger chili (optional)
Steamed rice, for serving

Instructions

Put the pork in a large heavy pot and add the water. Bring to a boil over medium-high heat. Skim off the gray foam that rises during the first 5–10 minutes for a clearer broth.
Add the onion and tomatoes. Lower the heat to maintain a gentle simmer, partly cover, and cook for 60–75 minutes, until the pork is tender. Check a piece with a food thermometer: USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of pork; for this soup, continue simmering until the meat is also tender enough to eat comfortably. Add a little hot water if needed to keep the pork mostly submerged.
Stir in the sinigang mix and fish sauce. Start with the packet amount recommended for the volume of broth you have; simmer for 2 minutes, then taste. Add more mix a little at a time if you want a sharper sourness, following the packet’s directions, and adjust the fish sauce if the broth needs more savory depth.
Add the daikon and simmer for 5 minutes. Add the eggplant and long beans and simmer for another 5–7 minutes, until the vegetables are just tender. Add the optional chili with the vegetables for mild heat.
Turn off the heat and stir in the water spinach. Let it wilt in the hot broth for 1–2 minutes. Taste once more and adjust the sourness or saltiness before serving.

Tips

Use the packet’s dilution directions as your guide. Sinigang mixes vary in saltiness and sourness, so add the powder gradually rather than assuming every packet tastes alike.
For a less fatty soup, chill the cooked broth until the fat solidifies, lift it off, then reheat the broth and continue with the seasoning and vegetables. This adds chilling time, so it is best done ahead.
If water spinach is unavailable, baby spinach is an easy stand-in. It wilts quickly and has a softer texture; add it right at the end. Bok choy is another option, but give its thicker stems a few minutes in the broth first.
Keep the simmer gentle after the pork comes to a boil. A hard boil can make the broth cloudy and break up the meat before the vegetables are ready.

Serving Suggestions

Serve the soup hot in deep bowls, with steamed white rice on the side or spooned directly into the broth. Put extra fish sauce and sliced chili on the table for anyone who wants a saltier or spicier bowl. Sinigang is substantial enough to serve as a meal; a simple plate of sliced cucumber or fresh fruit makes a light accompaniment.

Variations

Families and regions vary the vegetables, cut of pork, and level of sourness. Pork shoulder gives a meatier, less bony bowl; ribs provide bones that enrich the broth. You can replace daikon with taro, which becomes soft and creamy, or add okra with the eggplant and beans. Avoid adding every vegetable at once: use the timing in the recipe as a guide and adjust for size and tenderness.

If you cannot find sinigang mix, use a tamarind-based soup paste or concentrate, adding it gradually and tasting as you go; products differ in strength, so follow their label directions. Tamarind gives a related tang but may taste fruitier and less consistent than a prepared mix. Fresh tamarind pulp can also be simmered in the broth and strained, though it takes extra preparation and the sourness will vary.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking in shallow, covered containers. The soup keeps for 3–4 days in the refrigerator. For longer storage, freeze it in airtight containers for up to 2–3 months for best quality; vegetables may soften after thawing. Thaw overnight in the refrigerator or reheat from frozen over low heat with a splash of water.

Reheat only the portion you plan to eat, bringing it to 165°F (74°C), measured with a food thermometer. Heat gently on the stove, stirring so the broth warms evenly; avoid prolonged boiling, which can make the vegetables overly soft. Discard soup left 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 make sinigang na baboy without the packet?
Yes. Tamarind paste, concentrate, or cooked tamarind pulp can provide sourness, but their strength varies. Add a small amount, simmer, and taste before adding more; you may also need to adjust the salt and savory seasoning.

When should I add the sinigang mix?
Add it after the pork is tender, before adding the vegetables. This lets you taste and adjust the broth without overcooking the vegetables. Follow the product label for the amount, since packet sizes and strengths differ.

What cut of pork works best?
Bone-in spare ribs are flavorful and become tender during a long simmer. Pork shoulder is a good alternative if you prefer more meat and fewer bones; cut it into similar-sized pieces so it cooks evenly.

Why is my sinigang too sour or too salty?
Different brands of mix vary, and the broth reduces as it simmers. Add the mix in stages and taste before adding the full amount. If it is already too strong, dilute with hot water or unsalted broth, then readjust gradually.

Can I prepare it ahead?
Yes. Cook the pork and broth ahead, refrigerate within 2 hours, and keep the vegetables separate if you want them firmer. Reheat the broth and pork to 165°F (74°C), then cook the vegetables in it just before serving.

Can I use frozen vegetables?
Yes, though they can soften faster than fresh vegetables. Add them near the end and simmer only until heated through and tender. Add leafy greens last, allowing the residual heat to wilt them.
