This classic Cantonese steamed pork patty is tender, juicy, and deeply savory from fermented salted fish. Ginger, scallion, Shaoxing wine, and a little sesame oil make the pork fragrant, while the steaming juices become a rich sauce for rice.
Finely mince the ground pork again with a knife or cleaver until it looks slightly pasty. Place it in a mixing bowl and add the sesame oil, salt, white pepper, baking soda, Shaoxing wine, water, cornstarch, grated ginger, minced scallion, and water chestnuts, if using.
Stir the pork mixture firmly in one direction with a fork or chopsticks until it becomes sticky, smooth, and cohesive. Cover and marinate in the refrigerator for 1 hour.
Spread the pork mixture into a thin, even patty in a deep heatproof plate or shallow bowl. Use a deep dish because the pork will release flavorful juices as it steams.
Arrange the salted fish slices over the pork. If your salted fish is very salty or you are using more than 6 slices, reduce the added salt in the pork mixture.
Scatter the julienned ginger and scallion over the top. Place the dish in a preheated steamer and steam over medium-high heat for about 10 minutes, or until the pork is cooked through.
Turn off the heat and let the dish rest in the steamer for 2 to 3 minutes. Spoon the savory steaming juices over the pork before serving with hot rice.
Use pork with some fat for the juiciest texture; very lean pork can turn firm and dry. Salted fish varies widely in saltiness, so start with less salt in the pork mixture if unsure. Water chestnuts are optional but add a pleasant crunch. Store leftovers in an airtight container in the refrigerator for up to 2 days and reheat gently by steaming or microwaving with a splash of water.
