Step 1

Put the egg, pork, chives, cabbage, garlic, ginger, soy sauce, Shaoxing wine, sesame oil, cornstarch, sugar and white pepper in a large bowl. Mix well with your hands or a rubber spatula until well combined.

Step 2

Fill a small bowl with cold water. Set a dumpling wrapper on a clean surface (keep the rest covered with a damp paper towel so they don't dry out). Scoop two teaspoons of the filling into the center of the wrapper. Dab a finger into the water and brush along the edges of the wrapper, about 1/4 inch of the rim. Fold the wrapper in half over the filling to create a half-moon. Gather a corner of the dumpling and pinch to form a seal. Using your index finger as a guide, create four to five equally-spaced pleats until you reach the other corner of the wrapper. Press down to seal that other corner. If the wrapper isn't sealing, add a small dab of water to help it seal. Transfer to a baking sheet and cover with a damp paper towel while you form the remaining dumplings.

Step 3

Heat 1 tablespoon vegetable oil in a large nonstick skillet over medium-high heat. Working in batches, add the dumplings in a single layer. Add 1/3 cup water and reduce the heat to medium-low. (If using a medium skillet, add 1/4 cup water.) Cover with a lid (preferably glass) and cook until the wrappers become slightly opaque, 4 to 5 minutes. Uncover and cook until most of the liquid evaporates, then cook over medium heat until the bottoms are crisp and golden brown, 2 to 3 minutes. Loosen the dumplings from the skillet with a spatula and transfer to a serving plate. Repeat with the remaining dumplings, adding 1 tablespoon vegetable oil in between batches.

Step 4

Drizzle chile crisp over the pan-fried dumplings and serve with a side of Chinese black vinegar, if desired. Enjoy while warm.
