This savory Chinese steamed pork patty is tender, juicy, and deeply seasoned with ginger, oyster sauce, Shaoxing wine, and salted duck eggs. The rich yolks melt into the pork as it steams, making it perfect with a bowl of hot rice.
Crack the salted duck eggs and separate the yolks from the whites. Place the yolks in one bowl and the whites in another. If using salted duck egg yolks only, replace the whites with 1/2 cup water mixed with 3/4 tsp salt.
In a shallow heatproof dish, combine the ground pork, minced ginger, cornstarch, sugar, white pepper, five-spice powder, Sichuan peppercorn powder, oyster sauce, water, Shaoxing wine, sesame oil, and reserved salted egg whites.
Stir firmly with chopsticks or a spatula in one direction until the pork becomes sticky, smooth, and paste-like. Fold in the chopped water chestnuts and scallions until evenly distributed.
Smooth the pork mixture into an even layer in the steaming dish. Let it marinate for at least 30 minutes so the seasonings can absorb into the meat.
Cut each salted duck egg yolk in half. Arrange the yolks cut-side down or rounded-side up across the surface of the pork patty. Prepare a steamer and bring the water to a steady boil.
Place the dish in the steamer, cover, and steam over medium-high heat for 20 minutes, or until the pork is fully cooked. Turn off the heat and let it rest, covered, for 5 to 10 minutes before serving.
Garnish with chopped scallion or cilantro. Serve hot with steamed rice, spooning any savory juices from the dish over the rice.
Use pork with some fat for the juiciest texture; very lean pork can steam up firm and dry. Stirring the meat until sticky is important because it helps the patty bind and stay tender. If your salted duck eggs are especially salty, reduce or omit the added salt substitute. Leftovers can be refrigerated in an airtight container for up to 3 days and reheated by steaming or microwaving gently.
