Sinigang Mix Grams: How Much to Use in Soup

Sinigang is a Filipino sour soup, often made with pork, vegetables, and a tart tamarind-based broth served hot with rice. For this version, start with 40 g of sinigang mix for about 1.4 L of water, then adjust the sourness gradually because packet sizes and salt levels vary.

Ingredients

2 lb pork shoulder, cut into roughly 1½-inch (4 cm) pieces (900 g)
6 cups water (1.4 L), plus a little extra if needed
40 g powdered sinigang mix, divided; check the packet directions if its recommended water amount differs
1 medium yellow or red onion, peeled and cut into wedges (about 5 oz / 150 g)
2 medium ripe tomatoes, cut into wedges (about 10½ oz / 300 g)
1 tablespoon fish sauce (15 ml), plus more to taste
8 oz daikon radish, peeled and cut into thick half-moons (225 g)
1 small Asian eggplant, cut into 1-inch (2.5 cm) pieces (about 7 oz / 200 g)
6 oz green beans, trimmed and cut into 2-inch (5 cm) lengths (170 g)
1 bunch water spinach, also called kangkong, trimmed and cut into manageable lengths (about 5 oz / 150 g); or use baby spinach
1–2 small long green chilies, whole or slit lengthwise, optional (about 10–20 g)
½ teaspoon fine salt (about 3 g), only if needed after tasting
Cooked rice for serving, optional (about 1½ cups / 280 g uncooked rice, cooked according to its package)

Instructions

Prepare the ingredients. Cut the pork into similar-sized pieces so they cook evenly. Wedge the onion and tomatoes, slice the daikon and eggplant, and trim the beans and water spinach. Keep the leafy greens separate from the firm vegetables; they need only a brief time in the pot.
Start the pork broth. Put the pork, water, onion, tomatoes, and fish sauce in a large heavy pot. Bring the liquid just to a boil over medium-high heat, skimming off any gray foam that rises. Lower the heat until the broth maintains a gentle simmer, cover the pot partly, and cook for 60 minutes. Avoid a hard boil, which can make the broth cloudy and the meat less tender.
Check the pork and add the daikon. Use a food thermometer to check a large piece of pork. USDA FSIS guidance sets the safe minimum for whole cuts of pork at 145°F (63°C) followed by a 3-minute rest; for this soup, continue simmering beyond that point until the pork is tender when pierced. Add the daikon and simmer for 8 minutes. If the pork is not yet tender after the first hour, keep cooking and check it every 10 minutes; add water if the broth has reduced more than you want.
Season with the mix in stages. Stir 30 g of sinigang mix into the broth until dissolved. Taste a spoonful after it has simmered for a minute. Add the remaining 10 g in small increments, tasting between additions, until the broth is sour enough for you. The full 40 g is a useful starting quantity for 1.4 L of water, not a rule for every brand. Some packets are more concentrated, saltier, or intended for a different volume of liquid.
Cook the remaining vegetables. Add the eggplant, green beans, and optional chilies. Simmer gently for 5–7 minutes, until the vegetables are tender but still hold their shape. Add the water spinach and cook for 1–2 minutes, just until wilted. If using baby spinach instead of kangkong, add it at the end and stir until it wilts.
Finish and serve. Taste the broth before adding salt; the mix and fish sauce may already provide enough. Add a little more fish sauce for savory depth or a splash of water if the broth tastes too sharp or salty. Let the cooked pork rest in the hot broth for at least 3 minutes, then serve the soup hot with rice if desired.

Tips

Use grams for the mix, not packet count alone. Sachets are sold in different sizes, and their recommended water amounts can differ. Weigh 40 g when possible and compare it with the package directions. If the packet calls for less water than this recipe, follow its guidance or add the powder gradually and stop when the broth tastes balanced.
Build sourness slowly. Begin with 30 g, then add the rest a little at a time. You can increase the tartness, but you cannot take the mix back out. If you accidentally make the broth too sour, add hot water a little at a time and correct the seasoning with a small amount of fish sauce.
Keep the simmer gentle. A steady, low simmer helps the pork become tender without breaking the vegetables apart. Add the leafy greens last; boiling them for a long time makes them lose their fresh texture and color.
Adjust salt at the end. Many mixes contain salt, and fish sauce is salty too. Taste after adding both before reaching for salt. If kangkong is hard to find, baby spinach is a practical substitute; it is softer and less stemmy, so add it right before serving.

Serving Suggestions

Serve sinigang in deep bowls with plenty of broth, a piece of pork, and a mix of vegetables in each portion. Steamed white rice is the usual accompaniment: spoon some rice into the bowl or serve it alongside so each person can combine it with the sour broth. If you like a sharper, salty accent, put a small dish of fish sauce with sliced fresh chili on the table; diners can season their own portions rather than making the whole pot hotter.

For a simple meal, the pork and vegetables make the soup substantial enough on their own, while rice makes it more filling. Keep extra rice separate from the pot, since rice left sitting in the soup absorbs broth and softens. A small plate of sliced cucumber or another crisp vegetable can provide a cool contrast, but it is optional rather than necessary.

Variations

Use a different cut of pork. Pork ribs can replace shoulder, though their shape and cooking time vary; simmer until the meat is tender and check a thick piece with a thermometer. Pork belly gives a richer, fattier broth, while leaner pork loin cooks faster and can become dry if simmered for the full time. If using loin, add it later and cook only until done and tender enough for your preference.

Make a seafood version. Replace the pork with firm fish pieces or peeled shrimp and make the broth with onion, tomato, and water before adding the mix. Add fish near the end and cook it until it reaches 145°F (63°C), the USDA FSIS safe minimum for fish; shrimp should be opaque and firm. Seafood cooks much faster than pork, so do not follow the long pork simmer for the seafood itself.

Choose other vegetables. Radish, eggplant, green beans, and kangkong are common choices, but families and regions use different combinations. Okra, taro, or bok choy can also work. Taro needs enough simmering to become tender, while bok choy and other leafy greens should go in near the end. If using a vegetable with a strong flavor or a lot of water, add it in modest amounts and taste the broth again.

Use fresh tamarind instead of a packet. Simmering fresh tamarind pods and straining the pulp can provide sourness, but it will not taste exactly like a seasoned powdered mix. Fresh tamarind generally contributes less of the packet’s salt and other seasoning, so add fish sauce and salt cautiously and season to taste. There is no exact gram-for-gram conversion because the sourness of fresh pods varies.

Storage and Reheating

Let leftovers cool enough to pack, then refrigerate them within 2 hours of cooking in shallow, covered containers. Store the soup for 3–4 days in the refrigerator. If possible, keep rice in a separate container. The vegetables will soften as they sit in the broth, but the soup remains useful for another meal within that refrigerated window.

Reheat only the amount you plan to eat, either in a saucepan over medium heat or in a microwave-safe bowl. Stir occasionally and heat leftovers to 165°F (74°C), checking the center with a food thermometer. Bring the broth to a gentle simmer, but avoid prolonged boiling, which can make the vegetables mushy. Add a splash of water if the broth has become too concentrated, then taste and adjust the seasoning. For longer storage, freeze cooled portions in airtight, freezer-safe containers; thaw in the refrigerator and reheat to 165°F (74°C). Texture may soften after freezing, especially for the greens and eggplant.

Frequently Asked Questions

How many grams of sinigang mix should I use per liter of water?
Use about 28–30 g per liter as a starting ratio. This recipe uses 40 g for 1.4 L, or roughly 29 g per liter. Check the packet’s directions because brands can differ, and add the powder gradually so you can stop at the sourness and salt level you prefer.

Is 40 g of sinigang mix the same as one packet?
Not always. Packet sizes vary, so weigh the contents or read the net weight printed on the sachet. If your packet contains more or less than 40 g, use the package’s suggested water amount as a guide and taste the broth before adding all of the powder.

Can I make sinigang mix less sour?
Yes. Start with 25–30 g for this pot, taste, and add more in small increments only if needed. If the soup is already too sour, dilute it with a little hot water and adjust the savory seasoning carefully. Adding extra sugar is not a direct substitute for reducing the sourness and can change the flavor.

Can I use sinigang mix with chicken or vegetables?
Yes. The mix can season chicken or a vegetable-only soup, but cooking times change with the ingredients. For chicken, use a thermometer and cook poultry to the USDA FSIS safe minimum of 165°F (74°C). For vegetables, simmer firm items until tender and add leafy greens near the end; start with less mix and adjust to the amount of broth.

Why does my sinigang taste too salty?
The mix and fish sauce both contribute salt, and simmering can concentrate the broth. Add no salt until the soup is finished, and use less fish sauce if the packet is already salty. If the pot is over-seasoned, add hot water a little at a time, then taste again before making any further changes.

Can I add the whole packet at the beginning?
You can, especially if the package gives a clear water ratio and you already know you like that level of sourness. For a first attempt, it is safer to add most of it after the pork broth is made and finish in increments. That way, the final taste reflects the actual amount of liquid in your pot, including any broth lost to simmering.
