Sinigang na Baboy with Gabi: A Tangy Pork Soup

Sinigang na baboy with gabi is a Filipino pork soup simmered with sour tamarind, vegetables, and taro, which thickens the broth to a pleasantly silky consistency. Its bright, savory flavor is especially satisfying with steamed rice; sourness and vegetable choices vary from cook to cook.

Ingredients

2 lb (900 g) bone-in pork shoulder or pork ribs, cut into serving-size pieces
10 cups (2.4 L) water, plus more if needed
1 medium yellow onion (about 6 oz/170 g), peeled and quartered
2 medium tomatoes (about 10 oz/280 g), quartered
1 tablespoon (15 ml) fish sauce, plus more to taste
8 oz (225 g) gabi (taro root), peeled and cut into 1½-inch (4 cm) chunks
1 packet (about 1.4 oz/40 g) sinigang sa sampalok (tamarind soup) mix, or enough to taste; follow the packet’s directions if its size differs
1 medium daikon radish (about 10 oz/280 g), peeled and sliced into ½-inch (1 cm) rounds
1 small eggplant (about 8 oz/225 g), cut into 2-inch (5 cm) pieces
8 oz (225 g) long green beans, trimmed and cut into 2-inch (5 cm) lengths
2 green finger chilies (siling haba), left whole, optional
1 bunch water spinach (about 8 oz/225 g), tough ends trimmed and leaves and tender stems cut into 3-inch (7.5 cm) lengths
Freshly ground black pepper, to taste

Instructions

Put the pork in a large pot and add the water. Bring to a boil over medium-high heat, skimming off the gray foam that rises. Add the onion and tomatoes, lower the heat, and simmer gently, partially covered, for 45 minutes. Keep the liquid at a steady simmer, not a hard boil, so the pork cooks tender without the broth evaporating too quickly.
Add the gabi and simmer for 15 minutes, until a fork slides into the pieces easily. As it cooks, some taro may soften and break down into the broth, giving it body. Avoid stirring vigorously if you want the remaining chunks to hold their shape.
Stir in the fish sauce and tamarind mix. Start with the amount on the packet or a little less, then adjust after the vegetables cook; packet strengths vary. Add the daikon and eggplant and simmer for 8 minutes.
Add the green beans and whole chilies, if using. Simmer for 5 minutes, then add the water spinach and cook for another 2–3 minutes, just until wilted and tender. Check a thick piece of pork with a food thermometer: 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 fork-tender, which generally takes it well beyond that minimum. If the pork is not tender, remove the vegetables with a slotted spoon and simmer the meat longer, adding the vegetables back to warm through.
Taste the broth. Add more tamarind mix for sourness, fish sauce for savory saltiness, or a little hot water if it is too concentrated. Season with black pepper. Serve hot, with the pork, vegetables, and broth in each bowl.

Tips

Choose the right pork: Bone-in shoulder or ribs add flavor and become tender during a slow simmer. Lean pork loin cooks faster but can turn dry and is less suited to extended simmering.
Handle gabi carefully: Peel it with a knife or peeler and avoid rubbing your eyes after handling raw taro. Cook gabi fully; raw or undercooked taro can irritate the mouth and throat. Frozen peeled taro can be used from frozen; allow extra simmering time as needed.
Adjust sourness gradually: Tamarind soup mix varies by brand, so taste before adding more. If you cannot find it, use tamarind concentrate diluted according to its label, or unsweetened tamarind pulp simmered in water and strained. Fresh tamarind usually gives a less uniform, sometimes fruitier sourness; lemon or lime juice is a last-resort substitute and tastes sharper.
Keep vegetables distinct: Add them in stages rather than all at once. A gentle simmer and late addition keep the greens and beans from becoming mushy.

Serving Suggestions

Ladle the soup into deep bowls so everyone gets pork, gabi, vegetables, and plenty of broth. Serve with steamed white rice, either alongside or spooned into the soup. Offer extra fish sauce with sliced chilies for diners who want more salt or heat; a small squeeze of calamansi can brighten a bowl, though the broth is already sour.

Variations

For a more traditional souring base, simmer fresh tamarind pods until soft, mash them in their cooking liquid, and strain the liquid into the pot. Start with a modest amount and adjust to taste. Green mango or kamias can also add sourness, but each gives the broth a different fruit-like character. If water spinach is unavailable, use baby spinach, adding it at the very end; it wilts faster and is more delicate. Mustard greens are another option, with a sharper, peppery flavor. For a leaner soup, use pork shoulder with excess surface fat trimmed, though some fat helps season the broth.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking in shallow, covered containers. Keep them refrigerated at 40°F (4°C) or below and use within 3–4 days; for longer storage, freeze in airtight containers for up to 2–3 months for best quality. The gabi may soften further after storage. Reheat only the portion you plan to eat on the stovetop until steaming throughout and at least 165°F (74°C), checking with a food thermometer, or microwave it covered, stirring partway through and checking the temperature in several places. Do not leave the soup at room temperature for more than 2 hours, or 1 hour if the temperature is above 90°F (32°C).

Frequently Asked Questions

Can I make sinigang na baboy without gabi?
Yes. Leave it out and the broth will be thinner, without gabi’s soft, starchy texture. You can still make the soup with pork, tamarind, and the vegetables.

How do I know when the pork is tender?
A fork should pierce the meat easily, and it should separate without much effort. The time depends on the cut and size of the pieces; simmer longer if necessary, keeping the pot covered and adding water if the broth gets low.

Can I use a different souring agent instead of packet mix?
Yes. Tamarind pulp or concentrate is a good substitute, but its strength varies, so strain pulp and add the sour liquid a little at a time. Calamansi, lemon, or lime will taste sharper and less like a tamarind-based broth.

When should I add the vegetables?
Add firm vegetables first and tender greens last. Daikon and eggplant need several minutes to soften, while long beans take only a few minutes and water spinach usually needs just 2–3 minutes.

Can I prepare the soup ahead?
Yes. You can simmer the pork and broth ahead, cool and refrigerate them promptly, then bring the soup back to a simmer before adding or reheating the vegetables. Refrigerate within 2 hours and reheat leftovers to 165°F (74°C).

Is this soup supposed to be very sour?
There is no single required sourness level. Begin with less tamarind mix than you think you need, taste the broth after the vegetables cook, and add more until it suits you.
