Sinigang na Shrimp Ingredients and Easy Cooking Guide

Sinigang na hipon is a Filipino sour shrimp soup, usually made with tomatoes, onion, vegetables, and a tamarind-based broth. The tart, savory soup cooks quickly, so the shrimp stay tender while the vegetables bring color and texture; versions vary by household and by the souring ingredients available.

Ingredients

1½ lb (680 g) large shell-on shrimp, deveined; thaw frozen shrimp safely in the refrigerator
8 cups (1.9 L) water, divided
1 medium yellow onion (about 150 g), peeled and cut into wedges
2 medium ripe tomatoes (about 300 g), cut into wedges
1 packet (about 1.4 oz / 40 g) sinigang sa sampalok soup mix, or the amount specified on its package
1 small daikon radish (about 250 g), peeled and sliced into ¼-inch (6 mm) rounds
1 small eggplant (about 200 g), cut into 1-inch (2.5 cm) pieces
6 oz (170 g) long beans, trimmed and cut into 2-inch (5 cm) lengths
2 cups (about 60 g) fresh water spinach (kangkong), tough stems removed and leaves cut into 3-inch (7.5 cm) lengths; substitute baby spinach if unavailable
1–2 Thai bird’s-eye chiles, left whole (optional)
1 tablespoon (15 ml) fish sauce, plus more to taste
¼ teaspoon (1 g) fine salt, plus more to taste if needed
Steamed white rice, for serving

Instructions

Prepare the shrimp and vegetables. If the shrimp are frozen, thaw them in the refrigerator, not on the counter. Rinse and drain the shrimp, then keep them chilled while preparing the vegetables. Cut the onion, tomatoes, radish, eggplant, long beans, and water spinach as described above. Keep the leafy greens separate from the firmer vegetables.
Start the broth. In a large pot, bring 8 cups (1.9 L) water to a boil over high heat. Add the onion and tomatoes, reduce the heat to maintain a steady simmer, and cook for 8 minutes, until the tomatoes begin to soften and release their juices.
Season and cook the firm vegetables. Stir in the sinigang mix, starting with the packet’s suggested amount if it differs from the quantity listed. Add the radish, long beans, optional whole chiles, and fish sauce. Simmer uncovered for 7 minutes, until the radish is beginning to turn tender but still holds its shape.
Add the eggplant. Stir in the eggplant and simmer for 4 minutes. Taste the broth; add a little more sinigang mix for a tarter soup, or water if it is too intense. Season with salt only after tasting, since the soup mix and fish sauce may already be salty.
Cook the shrimp. Add the shrimp and simmer gently for 2–4 minutes, depending on their size, turning them once if needed. Check the thickest shrimp with a food thermometer: the USDA FSIS safe minimum internal temperature for fish and shellfish is 145°F (63°C). The shrimp should also be opaque and firm, not tightly curled or rubbery.
Finish with greens and serve. Stir in the water spinach and cook for 1 minute, just until wilted. Turn off the heat and taste the broth once more, adjusting with fish sauce, salt, or a small splash of water. Serve hot with steamed rice.

Tips

Use the packet as a guide. Sinigang mixes vary in saltiness and sourness. Add most of the packet first, taste after it dissolves, and add more gradually rather than seasoning the broth all at once.
Keep the shrimp tender. Shrimp need only a few minutes in simmering broth. Check them as they turn opaque and use a thermometer; boiling them hard or leaving them in the hot pot after cooking can make them tough.
Choose a substitute with its flavor in mind. Fresh kangkong is traditional, but baby spinach wilts quickly and tastes milder. If you cannot find sinigang mix, use tamarind paste diluted in water and add it gradually; the result may lack the seasoning and depth of a prepared mix, so balance with fish sauce and salt.
Prep ahead, finish later. Chop the vegetables several hours ahead and refrigerate them separately. For the best texture, cook the soup and add shrimp shortly before serving rather than letting shellfish sit in hot broth.

Serving Suggestions

Serve sinigang na hipon in deep bowls with plenty of broth, vegetables, and shrimp. Put steamed white rice on the side or spoon the soup over rice, as many Filipino meals do. A small dish of fish sauce with sliced fresh chiles can be offered for diners who want extra salt or heat. The soup is filling as a main meal, so a simple side of fresh fruit or a lightly dressed vegetable salad is enough.

Variations

Use fresh tamarind. Simmer peeled tamarind pods in water until soft, mash them, then strain the liquid into the broth. Add it a little at a time to reach the desired tartness; the exact quantity depends on the fruit. This gives a less standardized flavor than soup mix and may need additional fish sauce and salt.

Change the souring agent. Guava, calamansi, green mango, or bilimbi can sour sinigang in some regional and family versions. Each changes the aroma and character of the broth, so add the fruit gradually and taste as it cooks.

Swap the vegetables. Taro, okra, or green beans can replace some of the listed vegetables. Add sturdy vegetables early enough to soften, and add tender greens at the end. If using taro, cook it until completely tender.

Make it milder or hotter. Leave out the bird’s-eye chiles for a gentle soup, or serve sliced chiles separately. For a richer broth, some cooks add a few pieces of fatty pork, which will change the cooking time and flavor; cook the pork fully before adding the shrimp.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking in a covered, shallow container. For best quality, store the broth and shrimp together for no more than 3–4 days at 40°F (4°C) or colder. The shrimp may become firmer after storage, and the vegetables will soften further. Freeze leftovers in a suitable airtight container for up to 2–3 months for best quality, though the vegetables may lose texture when thawed.

Reheat only the portion you plan to eat on the stove over medium heat, stirring gently, or in a microwave-safe covered dish. Bring leftovers to 165°F (74°C), as recommended for reheating, and check with a food thermometer. Avoid repeatedly warming and cooling the full pot; discard soup left at room temperature for more than 2 hours (or 1 hour above 90°F / 32°C).

Frequently Asked Questions

Can I use frozen shrimp?
Yes. Thaw it in the refrigerator, then drain and add it to the simmering soup. You can cook shrimp from frozen, but it releases extra water and cooks less evenly, so thawing first makes it easier to control the broth and doneness.

Do I need to peel the shrimp?
No. Shell-on shrimp add flavor to the broth and are common in this soup. Devein them before cooking if desired, and let diners peel them at the table. Peeled shrimp are easier to eat but can give a less savory broth.

What can I use instead of sinigang mix?
Use strained tamarind liquid or tamarind paste diluted with water, adding it in small amounts until the broth is pleasantly sour. Then adjust fish sauce and salt. Lime or lemon can add acidity in a pinch, but their flavor is sharper and less like tamarind.

How do I know when the shrimp are cooked?
Check the thickest part with a food thermometer; shellfish should reach 145°F (63°C). The flesh should be opaque and firm. Remove the pot from the heat as soon as they reach the safe temperature to avoid overcooking.

Can I make the soup ahead?
Prepare the broth and vegetables ahead, cool and refrigerate them promptly, then reheat the soup and cook the shrimp and greens just before serving. If the shrimp are already cooked, keep them refrigerated and add them only long enough to heat through, checking that reheated leftovers reach 165°F (74°C).

Is sinigang na hipon always made with tamarind?
No. Tamarind is a familiar souring choice, but sinigang varies by region, household, and available fruit. Other souring ingredients can be used, and the resulting broth will have its own distinctive taste.
