Sinigang na Baka Ingredients and How to Cook It

Sinigang na baka is a Filipino beef soup simmered with vegetables in a savory, distinctly sour broth, usually served hot with rice. Beef shank gives the soup body and flavor, while tamarind provides the tang; vegetables and souring agents vary by household and region.

Ingredients

2½ lb (1.13 kg) bone-in beef shank, cut into serving-size pieces; ask the butcher to saw through the bones
10 cups (2.4 L) water, plus a little more if needed
1 medium yellow onion (about 7 oz/200 g), peeled and quartered
2 medium tomatoes (about 10 oz/280 g), quartered
2 tablespoons (30 ml) fish sauce, plus more to taste
1 packet sinigang sa sampalok mix, about 1.4 oz (40 g), or ½ cup (120 ml) tamarind concentrate; add gradually and adjust to taste
1 medium daikon radish (about 10 oz/280 g), peeled and cut into ½-inch (1.25 cm) half-moons
8 oz (225 g) green beans, trimmed and cut into 2-inch (5 cm) lengths
1 medium eggplant (about 8 oz/225 g), cut into 1-inch (2.5 cm) pieces
2 cups (about 75 g) fresh kangkong (water spinach), cut into 3-inch (7.5 cm) lengths; substitute baby spinach or Swiss chard if unavailable
2 green finger chiles, such as long green chiles, left whole (optional)
½ teaspoon (2.5 g) fine salt, only if needed after seasoning
Cooked white rice, for serving

Instructions

Put the beef in a large, heavy pot and cover with the 10 cups (2.4 L) water. Bring it just to a boil over medium-high heat, skimming off the gray foam that rises. Lower the heat to maintain a gentle simmer; avoid a hard boil, which can make the broth cloudy and the meat cook unevenly.
Add the onion and tomatoes. Partially cover the pot and simmer gently for about 1 hour 45 minutes, checking occasionally and adding hot water if the beef is no longer covered. The meat should be tender enough to pierce easily with a fork. Timing varies with the cut and size of the pieces.
Check the thickest pieces with a food thermometer. The USDA FSIS safe minimum for whole cuts of beef is 145°F (63°C) followed by a 3-minute rest; for this soup, continue simmering beyond that minimum until the shank is fork-tender. Keep the soup hot while you finish the vegetables.
Stir in the fish sauce and about three-quarters of the sinigang mix, or half the tamarind concentrate. Add the daikon and simmer for 8 minutes, until it is beginning to soften. Taste the broth, then add more souring agent in small amounts; packet strengths and tamarind products differ.
Add the green beans, eggplant, and whole chiles, if using. Simmer for 5–7 minutes, just until the vegetables are tender but still hold their shape. Stir in the kangkong and cook for 1–2 minutes, until wilted. Spinach may need less time.
Taste and adjust with more fish sauce for savory depth, souring mix or concentrate for tang, or a little salt if needed. If the broth tastes too sharp, add hot water a little at a time rather than extra sugar. Serve immediately with rice.

Tips

Use a gentle simmer. A rolling boil can toughen the meat before its connective tissue softens. If the shank is still chewy, give it more time rather than turning up the heat.
Season the sour broth gradually. Sinigang packets and tamarind concentrate vary in saltiness and acidity. Add most of the souring agent after the beef is tender, then taste before adding the rest.
Choose a suitable substitute for kangkong. Baby spinach is easy to find and wilts quickly, but it is softer and less substantial. Swiss chard is sturdier; add its stems with the green beans and its leaves near the end.
Keep vegetables from overcooking. Cut them into fairly even pieces and add them in stages as directed. For planned leftovers, you can cook the greens separately and add them to each bowl.

Serving Suggestions

Ladle the beef, vegetables, and broth into deep bowls and serve with steamed white rice. Put extra rice and fish sauce with sliced fresh chile on the table so everyone can adjust their portion. A small dish of fish sauce with calamansi or lime is another common accompaniment; add it sparingly, since the soup is already sour and salty.

Variations

Use fresh tamarind: Simmer about 8 oz (225 g) ripe tamarind pods in 2 cups (475 ml) water until soft, roughly 15 minutes. Mash and strain the mixture, pressing the pulp to extract the liquid, then add it to the soup gradually. The acidity varies, so taste as you go.

Try another beef cut: Bone-in short ribs or beef neck can work well, though their cooking times differ. Boneless chuck is also suitable but gives a less gelatin-rich broth. Simmer until tender rather than relying only on the clock.

Adjust the vegetables: Taro, okra, or extra tomatoes appear in some versions. Add taro early enough to become tender, and add okra near the end so it does not break down excessively. Regional and family recipes vary; keep the sour broth central and choose vegetables that cook at compatible rates.

Storage and Reheating

Refrigerate leftover soup in shallow, covered containers within 2 hours of cooking. It 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. Cool and freeze promptly rather than leaving the pot out to reach room temperature.

Reheat only the portion you need on the stovetop, stirring occasionally, until it reaches 165°F (74°C) throughout; check with a food thermometer. Bring the broth to a steady simmer, but avoid prolonged boiling, which can make the vegetables mushy. If the broth has thickened, add a splash of water. Thaw frozen soup overnight in the refrigerator or reheat it from frozen over low heat, stirring as it loosens.

Frequently Asked Questions

What cut of beef is best for sinigang na baka?
Bone-in shank is a good choice because its bones and connective tissue add body as it simmers, and the meat becomes tender with time. Beef neck and bone-in short ribs are useful alternatives.

Can I make sinigang na baka without a seasoning packet?
Yes. Use fresh tamarind, prepared as described in the variations, or tamarind concentrate. Add it in stages and adjust with fish sauce and salt, since a packet also supplies seasoning.

How do I keep the beef tender?
Maintain a gentle simmer and cook until a fork slides into the meat easily. If the beef remains chewy, it usually needs more simmering time; a vigorous boil will not make it tender faster.

Can I cook this in a pressure cooker?
Yes. Pressure-cook the beef, water, onion, and tomatoes according to your cooker’s instructions for beef shank, then release pressure as directed and check tenderness. Add the souring agent and vegetables afterward, simmering them uncovered until just tender so they do not turn to mush.

Why is my sinigang broth too sour?
Different tamarind products and seasoning mixes vary in strength. Dilute the broth with hot water a little at a time, then rebalance with a small amount of fish sauce if needed. Next time, start with less souring agent and add more after tasting.

Can I prepare the soup ahead?
Yes. The beef and broth can be cooked ahead and refrigerated within 2 hours, then reheated to 165°F (74°C). For the freshest texture, add the vegetables while reheating or cook delicate greens just before serving.
