Cantonese steamed minced pork is a shared pork patty, not a dumpling filling. Season the mince, spread it evenly on a shallow heatproof plate, and steam until the centre is safely cooked. Water chestnuts add crunch; preserved mustard adds salt and should not be treated as an unseasoned vegetable.
Ingredients for a mustard and water-chestnut pork patty
This version follows the proportions in Made With Lau’s steamed pork patty: 12 oz pork shoulder, 1.5 oz preserved mustard tuber, 4 oz water chestnuts, and 2 scallions. Season with 1 tablespoon oyster sauce, 1 teaspoon each sugar, sesame oil and chicken bouillon, 2 tablespoons cornstarch, and 1/4 teaspoon white pepper. Have 1 teaspoon corn oil for the plate and mixture.
Read preserved-vegetable and sauce labels before adding extra salt. Oyster sauce contains shellfish; sauces and bouillon may also contain soy or wheat. Use a heatproof plate that fits the steamer with clearance for lifting, and have a thermometer and plate gripper ready.

Mix for cohesion, not a rubbery paste
- Finely chop the pork. Cut the mustard small, crush the water chestnuts, and separate scallion whites from greens.
- Mix pork with the seasonings until tacky, then incorporate vegetables and scallion whites. Stop once evenly combined.
- Oil the plate and mix in the remaining measured oil. Flatten the patty evenly rather than building a thick central mound.
The important preparation detail is consistency across the plate. A thick centre and thin edges create different cooking conditions within the same patty. Before steaming, look across the surface from the side and redistribute any heap with the back of a spoon. Keep the raw-pork spoon away from the garnish and serving utensils.

Steam, check the centre, and serve with the juices
Load the plate after the water boils and cover. The source recipe uses about 15 minutes in its plate setup; this is a checking point, not a maximum safe cooking time. Dish material and thickness can change the result.
Ground pork must reach 160°F (71°C), following the official safe-temperature chart. Probe the thickest centre without touching the plate; continue steaming if it is below that temperature. Lift the lid away from your face.
Garnish with scallion greens and spoon the cooking juices over rice. If the patty is firm, note its thickness and the point at which it reached temperature before changing several ingredients next time. Do not undercook the next batch to compensate for a dry result.

Can I use store-ground pork?
Yes. It may produce a finer, denser patty than hand-chopped shoulder. Keep the same centre-temperature check. This dish and black-bean steamed spare ribs share a steamer, but not a cooking time. For another pork-and-shrimp preparation, see siu mai.
