Sinigang Mix Original: A Pork Sinigang Soup Recipe

Sinigang is a Filipino sour soup, often made with pork, vegetables, and a tangy tamarind broth. This version uses original sinigang mix for its signature sour flavor, with fresh tomatoes and vegetables adding depth and texture; it is served hot with rice.

Ingredients

1½ lb (680 g) boneless pork shoulder, cut into 1½-inch (4 cm) pieces
8 cups (1.9 L) water, plus a little extra if needed
1 medium yellow onion (about 150 g), peeled and cut into wedges
2 medium tomatoes (about 300 g total), cut into wedges
1 packet original sinigang soup mix (about 40 g; packet sizes vary)
1 small daikon radish (about 250 g), peeled and sliced into ½-inch (1 cm) rounds
1 medium eggplant (about 250 g), cut into 1-inch (2.5 cm) pieces
8 oz (225 g) long beans, cut into 2-inch (5 cm) lengths; or 8 oz (225 g) green beans
2 cups (about 75 g) fresh spinach, water spinach, or roughly chopped bok choy leaves
1 tablespoon (15 ml) fish sauce, plus more to taste
½ teaspoon (1 g) freshly ground black pepper
1 green finger chili or long green chili (about 10 g), left whole, optional
½ cup (75 g) sliced radish or extra tomato, optional, for serving

Instructions

Prepare the ingredients. Cut the pork into similarly sized pieces so they cook at about the same rate. Wedge the onion and tomatoes, slice the daikon, and cut the eggplant and beans. Keep the leafy greens separate because they need only a short time in the hot broth. If your soup-mix packet is larger or smaller than 40 g, start with the amount recommended on its label for about 8 cups (1.9 L) of broth.
Start the broth. Put the pork, water, onion, tomatoes, and pepper in a large heavy pot. Bring the water to a boil over medium-high heat, then lower the heat to maintain a gentle simmer. Skim off foam that gathers on top during the first 10 minutes. Cover the pot partially and simmer for 60 to 65 minutes, stirring occasionally, until the pork is tender when pierced with a fork. Add a splash of water if the pork is no longer mostly submerged.
Check the pork and add the souring mix. Use a food thermometer to check a thick piece of pork. USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of pork; this longer simmer should take the pieces well beyond that temperature and make them tender. Stir in the sinigang mix until it dissolves. Begin with the packet amount intended for this volume, or use less if you prefer a milder sour broth. Simmer for 2 minutes, then taste before adding salt or more mix.
Cook the firm vegetables. Add the daikon and whole chili, if using, and simmer for 5 minutes. Add the eggplant and long beans and simmer for another 7 to 10 minutes, until the vegetables are tender but still hold their shape. If you prefer very soft vegetables, give them a few extra minutes, but avoid prolonged boiling that can break up the eggplant and make the beans dull and limp.
Season and finish. Stir in the fish sauce and taste the broth. Add more fish sauce for savory depth, a little water if it is too sharp or salty, or a small amount of extra sinigang mix if you want a stronger sourness. Stir in the spinach or other leafy greens and cook for 1 to 2 minutes, just until wilted. Turn off the heat and let the soup stand for 3 minutes before serving.
Serve hot. Ladle pork, vegetables, and broth into bowls, distributing the ingredients evenly. Put extra sliced radish or tomato on the table if desired, along with steamed rice. The soup should taste distinctly sour, savory, and warm, rather than overwhelmingly salty or concentrated.

Tips

Adjust the mix gradually. The amount of sourness and salt varies between packets, and packet sizes differ. If you are uncertain, dissolve most of the amount suggested for your broth volume, taste, and add more in small increments. It is easier to increase the seasoning than to correct a broth that has become too salty.
Choose a cut that can simmer. Pork shoulder has enough connective tissue to become tender during a slow simmer. Lean pork loin cooks faster and can turn dry if simmered for the full time; if using it, simmer the broth first and add the pork later, checking for doneness and tenderness rather than following the shoulder timing.
Keep the vegetables in stages. Radish needs longer than leafy greens, so add the sturdy vegetables first and greens at the end. Cut pieces to a similar size, and remember that they continue softening briefly in the hot broth after you turn off the burner.
Use a practical substitute for harder-to-find produce. Water spinach, called kangkong, is a familiar leafy addition, but ordinary spinach or bok choy works when it is unavailable. Green beans can stand in for long beans. These swaps change the texture slightly, not the overall sour-soup character.

Serving Suggestions

Serve sinigang in deep bowls while the broth is steaming, with a bowl of plain rice on the side. Some diners spoon rice into the soup; others eat it separately and alternate bites of rice, pork, and vegetables with sips of broth. Keep extra rice nearby because the sharp tamarind flavor is especially welcome with a simple, unsalted starch.

For a fuller Filipino-style meal, offer the soup with a small plate of sliced tomatoes, cucumber, or salted vegetables. A little fish sauce with sliced chili can be set out as an optional table condiment, but taste the soup first: the mix and the fish sauce may already provide enough salt. The broth is the focus, so rich or heavily seasoned side dishes are not necessary.

Variations

Use another protein. Beef short ribs or stewing beef work well but usually need a longer simmer, often 1½ to 2½ hours, before the vegetables go in. For beef, USDA FSIS recommends 145°F (63°C) with a 3-minute rest for whole cuts; stew meat is commonly cooked longer for tenderness. Chicken pieces can also be used, but the safe minimum for poultry is 165°F (74°C), checked with a food thermometer. Adjust the cooking time to the cut and size rather than relying only on the clock.

Make a seafood version. Shrimp, firm fish, or a mix of seafood can replace the pork. Build the broth with water, onion, tomato, and the sour mix first; add seafood near the end so it does not overcook. Fish should reach 145°F (63°C), the USDA FSIS safe minimum. Shrimp should be opaque and firm; avoid a long simmer. Seafood versions are often lighter and cook much faster than this pork recipe.

Change the vegetable mix. Taro, okra, green beans, or additional radish are common choices in different household versions. Taro needs a longer cooking time than leafy greens, while okra softens quickly and can thicken the broth slightly. Add each vegetable according to its texture, and keep the total amount close to the recipe so there is enough broth to season everything.

Use fresh tamarind if you prefer. Original sinigang mix is a convenient, consistent souring base. If you have fresh tamarind pulp, simmer it separately in water, strain out the seeds and fibers, and add the strained liquid a little at a time. Fresh tamarind can taste fruitier and less salty than a packaged mix, so season the broth with fish sauce or salt only after tasting. Tamarind paste varies in strength, so there is no exact one-to-one swap for every packet.

Storage and Reheating

Cool leftover soup promptly and refrigerate it within 2 hours of cooking. Transfer it to shallow, covered containers so it chills more quickly, and keep it refrigerated for 3 to 4 days. If the soup has been sitting out longer than 2 hours, discard it rather than saving it. The broth may taste a little more sour the next day as the flavors settle, while the vegetables will soften further.

For longer storage, freeze the soup in airtight, freezer-safe containers for about 2 to 3 months for best quality. Leave room at the top for expansion. The pork and broth freeze well, though eggplant and leafy greens may become softer after thawing. If you plan ahead, you can freeze the broth and pork and add freshly cooked vegetables when reheating.

Thaw frozen soup overnight in the refrigerator or reheat it from frozen over low heat in a covered pot, stirring as it loosens. Reheat leftovers until the center reaches 165°F (74°C), checking with a food thermometer. Bring the soup to a gentle simmer rather than a hard boil, which can break down the vegetables and make the pork stringy. Add a splash of water if the broth has become too concentrated.

Frequently Asked Questions

What does original sinigang mix taste like?
It gives the broth a tart tamarind-like sourness with savory seasoning and salt. The exact balance depends on the product and packet size. Tomatoes, pork, and vegetables round out the flavor, but the finished soup should still taste clearly sour.

How much sinigang mix should I use?
This recipe is written for one packet of about 40 g in 8 cups (1.9 L) of water. Packets are not all the same size, so check the instructions on yours and use its recommended amount for the volume of broth. Start with less if you are sensitive to salt or prefer a gentler sour flavor, then adjust after tasting.

Can I make sinigang mix original without pork?
Yes. Use shrimp, fish, chicken, beef, or vegetables instead. The cooking time changes substantially: seafood goes in near the end, chicken must reach 165°F (74°C), and beef generally needs a longer simmer to become tender. Keep the same broth and vegetables, and season to taste.

Why is my sinigang too sour or too salty?
Mixes vary, and using a full packet without checking its suggested water amount can make the broth intense. Add hot water a little at a time to dilute it, then taste again. If it is not salty enough after dilution, add a small splash of fish sauce. Avoid adding sugar as a first fix; it changes the character without removing the excess salt.

Can I prepare the soup ahead?
Yes. You can make the broth and pork a day ahead, cool them promptly, and refrigerate them. Reheat until the soup reaches 165°F (74°C), then add fresh leafy greens near the end if you want them brighter and less soft. The vegetables can also be cooked ahead, but they will soften more during storage and reheating.

Can I make this recipe with water spinach or kangkong?
Yes. Add washed, cut water spinach at the very end and cook just until the leaves wilt and the stems begin to soften, usually 1 to 2 minutes. If you cannot find it, use ordinary spinach or bok choy leaves. The substitute changes the texture but keeps the soup’s familiar combination of sour broth, pork, and greens.
