Cantonese siu mai are open-topped dumplings with a cohesive pork-and-shrimp filling. Thin wrappers, drained mushrooms, and even portions matter more than elaborate pleats. The quantities below are an adaptation of published cook recipes, not a claim of YueCuisine kitchen testing.
Filling and wrappers for about 24 dumplings
Use 450 g ground pork, 225 g peeled shrimp, 3 small dried shiitake mushrooms, 24 thin Hong Kong-style wrappers, and finely minced carrot for the tops. For the pork seasoning, measure 1 tablespoon each cornstarch, Shaoxing wine, sugar, neutral oil, and oyster sauce; 1 teaspoon salt; 1/4 teaspoon white pepper; and 1/2 teaspoon sesame oil. This follows the filling proportions in Sarah Leung’s siu mai recipe, but omits its separate shrimp pretreatment. Yield depends on wrapper size.
Mix until the filling holds together
- Rehydrate mushrooms until pliable, discard tough stems, squeeze dry, and mince. Pat the shrimp dry and chop it.
- Mix pork with starch, wine, sugar, salt, and pepper until sticky. Fold in shrimp, mushrooms, oils, and oyster sauce. Keep the bowl cold while you work.
- Cook a small spoonful separately to check seasoning; never taste raw filling. Adjust the remaining mixture only after that sample is fully cooked.
Daddy Lau’s siu mai lesson emphasizes draining excess moisture and choosing thin wrappers. It uses a different seasoning mix: combining every ingredient from both recipes would over-season the filling.
Shape open tops and flat bases
Support a wrapper between thumb and forefinger, add roughly a tablespoon of filling, and raise the edges around it. Add a little more filling if needed, level the top, and flatten the base so it stands. Fold excess square corners against the sides. Cover unused wrappers to keep them pliable. Make the dumplings similar in width and height, rather than filling the last few twice as heavily.
Steam, then check the center
Place dumplings on perforated parchment or cabbage leaves with gaps. Start with boiling water and maintain steady steam without splashing water onto the filling. The Woks of Life gives 9 minutes for its fresh dumplings; use that only as an initial check, since size and equipment differ.
Probe the center of a large dumpling from the side with a thin-tip food thermometer. Because the filling includes ground pork, reach at least 160 F (71 C), following the official temperature guidance. Continue steaming if needed and check more than one dumpling. Steam burns are a separate hazard: open the lid away from your face and lift the basket with protection.
FAQ
Why does the filling fall apart?
Check whether it became sticky during mixing and whether the mushrooms or shrimp were wet. A loosely packed wrapper cannot compensate for a watery filling.
Are wonton wrappers suitable?
Thin Hong Kong-style ones are; thick potsticker wrappers give a different result. Fold square corners down rather than closing the top.
Check wheat, egg, shellfish, soy, and sesame labels. For a larger dim sum meal, compare the frozen dim sum buying checklist and add steamed pork ribs in a separate batch.
