Fish Siomai with Ginger: Steamed Dumplings That Hold Without Tough Fish

Fish siomai needs a filling that holds together without excess water or starch. Start with cold, well-drained white-fish fillet, then mix it evenly with ginger, spring onion, egg and a measured spoonful of cornstarch. Make a small cooked test portion before wrapping the batch so seasoning and firmness can be adjusted without tasting raw fish.

Ingredients and starting conditions

For approximately 24 small siomai, use 400 g skinless, boneless white fish fillet, 40 g finely chopped spring onion, 12 g grated ginger, one lightly beaten egg, 1 tablespoon cornstarch, 1 tablespoon soy sauce (or reduced-sodium alternative), 1 teaspoon sesame oil if wanted, 24 commercial siomai wrappers, and a little oil for the steamer liner. Keep the fish refrigerated while preparing the wrappers. Check that each wrapper is intended for steaming, not a dry baked pastry product.

Six-step home method

1. Inspect fillets carefully with fingers and tweezers for pin bones; mince by hand or pulse briefly while still cold. Do not turn fish into a watery puree. Mix ginger, spring onion, soy and egg in a separate cold bowl.
2. Fold fish into the aromatics, then sprinkle over the measured starch. Stir just until the mixture holds together. If visibly watery, chill it for ten minutes and drain free liquid rather than doubling the starch blindly.
3. Steam a teaspoon of filling until its centre reaches 71°C, then taste the cooked sample for seasoning and firmness. Keep the remaining mixture refrigerated during the test. Use a fresh clean spoon when adjusting the cold filling; never taste it raw.
4. Line a steamer with lightly oiled parchment pierced for steam circulation or clean cabbage leaves. Divide the filling among 24 wrappers, about 20–22 g each, adjusting to the wrapper size. Draw the sides up and leave the top open; keep the filling level consistent rather than forcing too much into a small wrapper.
5. Bring the steamer to steady steam, arrange dumplings with space between them and close the lid. Begin checking after 8–12 minutes, allowing longer if needed. Because this filling contains raw egg as well as fish, check that the centre of a large dumpling reaches 71°C; 63°C for plain fish is not the endpoint for this recipe.
6. Transfer cooked siomai with a thin spatula to a clean tray. Serve hot with calamansi and a small measured soy-vinegar dip. Keep any remaining raw filling in the refrigerator and steam the next batch promptly rather than holding it on the counter.

Why the cooking order matters

The successful siomai depends on four decisions: dry-enough fish, moderate mixing, an equal filling measure, and a lined steamer. Excess starch hides the fish; excess wrapper overlap leaves thick gummy folds. The test dumpling is particularly useful because soy sauces vary markedly in strength, and raw tasting is not appropriate.

Troubleshooting

• Filling slides out of wrapper: use the measured filling portion and draw wrapper sides up snugly. Excess bulk defeats open-top shape.
• Dumpling feels rubbery: reduce mixing and avoid extra cornstarch. Excess starch, heavy mixing or overcooking can make the filling dense.
• Wrapper sticks to steamer: line and lightly oil the tray while allowing steam openings. Soft wrappers bond to bare hot metal.
• Centre is undercooked: steam a little longer and check thickest filling. Wrapper colour alone does not prove fish and egg doneness.

Portions, substitutions and serving

A small amount of finely grated carrot may be added after squeezing out moisture, but watery vegetables must not dilute the filling. If using frozen fish, thaw it safely in the refrigerator and drain it before weighing 400 g of prepared flesh. Ground chicken is not a direct substitution: poultry dumplings must reach 74°C. Fish siomai is a starter or part of a meal, so four household portions depend on whether rice and vegetables are served alongside it.

Safe preparation and storage

The filling contains fish, egg and soy; wrappers and soy sauce may contain wheat, and sesame oil adds sesame. Read the actual labels. Keep filling cold, use clean utensils for cooked dumplings and verify 71°C in the filling. Refrigerate leftovers promptly and reheat them to 74°C. Source 1 Source 2 Source 3 Source 4
