Sinigang Without Sinigang Mix: A Tamarind-Based Recipe

Sinigang is a Filipino sour soup, often made with pork, tamarind, vegetables and a clear, savory broth served alongside rice. This version builds its tang from real tamarind pulp instead of a seasoning packet, so you can adjust the sourness and salt to taste. Ingredients and souring agents vary between regions and households, and this flexible pork version is one way to make the soup from scratch.

Ingredients

4 ounces (115 g) seedless tamarind pulp from a compressed block
1 cup (240 ml) boiling water, for soaking the tamarind
2 pounds (900 g) boneless pork shoulder, cut into roughly 1½-inch (4 cm) pieces
7 cups (1.65 L) water, for the soup
1 medium yellow onion, about 5 ounces (150 g), peeled and cut into wedges
4 garlic cloves, about ½ ounce (12 g), peeled and lightly crushed
2 medium tomatoes, about 10 ounces (300 g), cut into wedges
2 tablespoons (30 ml) fish sauce
1 medium daikon radish, about 8 ounces (225 g), peeled and cut into ½-inch (1 cm) half-moons
1 small Asian eggplant, about 8 ounces (225 g), cut into 1-inch (2.5 cm) pieces
6 ounces (170 g) green beans, trimmed and cut into 2-inch (5 cm) lengths
4 ounces (115 g) water spinach, also called kangkong, leaves and tender stems separated into manageable lengths
1 teaspoon (5 g) fine salt, plus more as needed
¼ teaspoon (0.5 g) freshly ground black pepper
2 long green chilies, about ¾ ounce (20 g), left whole or slit once, optional

Instructions

Soak and strain the tamarind. Put the tamarind pulp in a heatproof bowl and pour over the boiling water. Leave it for 10 minutes to soften. Mash the pulp with a fork or clean fingers, then press it through a fine-mesh strainer into a bowl, scraping the underside of the strainer to collect the thick liquid. Discard the fibrous seeds and solids. You should have a dark, tangy tamarind liquid; set it aside while you prepare the soup.
Start the pork broth. Put the pork, 7 cups (1.65 L) water, onion, garlic, tomatoes, fish sauce, salt and pepper in a large heavy pot. Bring to a boil over medium-high heat, which usually takes about 8 minutes. Skim off any gray foam that rises to the surface for a clearer broth. Lower the heat until the liquid is at a gentle simmer, partially cover the pot, and cook for 50 minutes. Keep the simmer steady rather than vigorous; a hard boil can make the broth cloudy and break up the pork.
Add the tamarind and daikon. Stir in the strained tamarind liquid and add the daikon. Simmer for 10 minutes, partially covered. Taste a spoonful of broth. Tamarind varies in strength, so if you prefer a sharper soup, add a little more tamarind liquid if you have it; if it is already quite sour, leave it as it is. The flavor should be tangy but still savory.
Cook the firmer vegetables. Add the eggplant and green beans, then simmer for about 8 minutes, or until the daikon is nearly tender and the beans are cooked but still hold their shape. Keep the pot at a gentle bubble and stir carefully so the pork and eggplant do not get crushed.
Finish the soup. Add the water spinach leaves and tender stems, along with the optional whole chilies. Cook for about 2 minutes, just until the greens wilt. Check one of the largest pork pieces 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; the pieces should also be fork-tender after the longer simmer. Let the soup stand for 3 minutes, then taste the broth and adjust with salt or a small splash of fish sauce. Serve hot.

Tips

Adjust sourness gradually. Tamarind blocks differ in how tart and concentrated they are. Strain the pulp well, then add the liquid in stages if you are unsure; it is easier to make the soup more sour than to undo an overly sharp broth. The tomatoes contribute some acidity, too.
Use a sensible substitute if needed. If you cannot find block tamarind, start with 2 tablespoons (30 ml) tamarind concentrate diluted in a little warm water, then taste and add more in small amounts. Concentrates vary considerably. In a pinch, use about ¼ cup (60 ml) lime juice, added gradually at the end; it gives a brighter, citrus-like sourness rather than tamarind’s deeper, rounded tang.
Keep vegetables in stages. Daikon needs longer than leafy greens, and eggplant can turn mushy if simmered for too long. Add each type according to its cooking time and check it as you go. If using spinach instead of water spinach, stir it in right at the end because it wilts quickly.
Season after the souring liquid goes in. Fish sauce and tamarind both shape the broth, and their intensity varies by product. Taste after adding the tamarind before adding more salt; adding salt too early can leave the finished soup overly salty.

Serving Suggestions

Serve sinigang hot in deep bowls, with a piece of pork, several vegetables and plenty of broth in each serving. Offer steamed white rice on the side; diners can spoon the soup over the rice or eat the two together. A small dish of fish sauce with sliced chili is a useful table condiment for anyone who wants extra salt or heat, but taste the soup first because it is already seasoned.

If you are serving a group, keep the pot warm over very low heat only until everyone is ready to eat, rather than boiling it for a long time. The vegetables continue softening in hot broth. Put extra rice on the table and let each person choose how much broth to ladle over it.

Variations

Make it with another protein. Bone-in pork ribs can replace the shoulder; allow extra simmering time if they are not tender after the listed 50 minutes, and check meat temperature with a thermometer. For a seafood version, use firm fish pieces or peeled shrimp and add them near the end so they do not overcook. Fish should reach 145°F (63°C) according to the USDA FSIS safe minimum. Seafood cooks much faster than pork, so make a separate, shorter-simmered broth rather than following the pork timing unchanged.

Change the vegetables. Taro, radish, okra or leafy greens can be used in combinations that suit what is available. Taro takes longer to soften than greens, so add it with the daikon; okra can go in with the eggplant. Kangkong is traditional in many versions but may be difficult to find. Spinach is a practical substitute, though its delicate leaves and mild flavor make the finish softer and less distinctive.

Make the broth more or less tangy. For an especially sour pot, add more strained tamarind a spoonful at a time. For a gentler broth, begin with about three-quarters of the strained liquid and add more only after tasting. Some cooks use other souring ingredients, such as green mango or guava, and different households balance sourness and seasoning in their own way.

Storage and Reheating

Refrigerate leftover soup within 2 hours of cooking, divided into shallow containers so it cools promptly. Keep it covered in the refrigerator for 3–4 days. The broth may taste even more integrated the next day, but vegetables will soften as they sit, especially leafy greens and eggplant. If you expect leftovers, you can cook only the portions of greens you plan to serve and add fresh greens when reheating the remaining broth.

For longer storage, freeze the cooled soup in airtight freezer-safe containers for up to 2–3 months for best quality. Leave a little room at the top for expansion. Thaw overnight in the refrigerator when possible. Reheat on the stovetop over medium heat, stirring occasionally, until steaming throughout and at least 165°F (74°C); check with a food thermometer. You can also reheat an individual portion in the microwave, stirring partway through and checking the temperature in more than one spot. Add a splash of water if the broth has reduced, then adjust the seasoning after it is hot.

Frequently Asked Questions

Can I make sinigang without sinigang mix?

Yes. This recipe uses strained tamarind pulp for the characteristic sour broth, with fish sauce, tomatoes and salt for savory balance. The packet mix is convenient, but it is not required. Since fresh tamarind and prepared concentrates vary in strength, taste the soup after adding the souring liquid and adjust it a little at a time.

Where can I find tamarind pulp?

Look for compressed tamarind pulp or a seedless tamarind block in Filipino or other Southeast Asian grocery stores, often near dried foods, sauces or soup ingredients. Some larger supermarkets carry it in an international aisle. Avoid confusing a block of pulp with sweetened tamarind candy or sauce; those products can make the soup too sweet or change its flavor.

Can I use tamarind paste instead of a block?

Yes, but use a small amount first because paste and concentrate are often much stronger than soaked block pulp. Begin with 2 tablespoons (30 ml), dilute it with warm water if it is very thick, and taste the broth before adding more. Check the label for added salt or sugar and account for those in the final seasoning.

Why is my sinigang bitter or too sour?

Very concentrated tamarind or too much tamarind liquid can make the soup aggressively sour. If the pulp was not strained, fibrous or seed fragments may also add an unpleasant taste. Add water or unsalted broth a little at a time to soften an overly intense pot, then rebalance with a small amount of fish sauce or salt. Next time, add the tamarind gradually and taste before using all of it.

Can I prepare sinigang ahead of time?

You can cook the pork broth and vegetables ahead, cool and refrigerate it promptly, then reheat it before serving. For the best vegetable texture, slightly undercook the vegetables or keep the leafy greens separate and add them during reheating. Store the soup in the refrigerator for no more than 3–4 days, and bring leftovers to 165°F (74°C) when reheating.
