These pork and celery dumplings are savory, juicy, and full of classic homemade flavor. Chinese celery adds a fresh herbal note that balances the rich pork filling, while the seasoned oil keeps every bite tender. Make them with store-bought wrappers for convenience or homemade dough for a fully from-scratch version.
If you want to make homemade wrappers, place the flour in a stand mixer fitted with the dough hook. With the mixer on low, gradually add the tepid water and mix until a dough forms. Knead for about 8 minutes, or knead by hand for about 10 minutes, until smooth. Cover and let the dough rest for 1 hour.
Place the minced Chinese celery in a bowl, sprinkle with the salt, and let it sit for 30 minutes to draw out excess moisture.
Meanwhile, make the seasoned oil. Add 3 tbsp vegetable oil and the Sichuan peppercorns to a small saucepan over medium heat. Once the oil begins to bubble gently, reduce the heat to medium-low and let it infuse for 10 minutes. Remove from the heat and cool completely. If you are skipping the peppercorns, heat the oil alone for 5 minutes, then cool.
Heat the remaining 1 tbsp vegetable oil in a small pan over medium heat. Add the carrot and cook for about 2 minutes, just until slightly softened. Let it cool completely.
Squeeze the celery very well to remove as much liquid as possible. Transfer it to a large bowl with the cooled carrot, scallions, ginger, ground pork, sugar, sesame oil, oyster sauce, and soy sauce.
Mix the filling on low speed with a paddle attachment, or stir vigorously in one direction with chopsticks or a wooden spoon. Gradually add the Shaoxing wine and water as you mix.
Continue mixing for 5 to 7 minutes, or until the filling becomes sticky, cohesive, and paste-like rather than loose or watery. Strain out the peppercorns, add the infused oil to the filling, and mix for 1 more minute until fully absorbed.
If using homemade dough, divide it into 15 to 20 g pieces and roll each piece into a ball. Flatten each one and roll it into a thin 3 1/2-inch round wrapper.
To shape the dumplings, place about 1 tbsp of filling in the center of each wrapper. If using store-bought wrappers, lightly moisten the edge with water. Fold and pleat the dumplings closed, pressing firmly to seal.
Arrange the finished dumplings on a parchment-lined tray with a little space between them so they do not stick. To freeze, place the tray in the freezer until the dumplings are firm, then transfer them to a freezer bag and store for up to 3 months.
Cook the dumplings using your preferred method. Boil for 6 to 8 minutes, steam for 8 to 10 minutes, or pan-fry until the bottoms are golden, then add a splash of water, cover, and cook until the filling is cooked through and the wrappers are tender.
Chinese celery has a stronger flavor than regular celery; if needed, substitute the tender inner stalks of standard celery and mince them very finely. Do not skip squeezing the salted celery, or the filling can turn watery. Mix the filling until sticky and emulsified for the juiciest texture. Frozen dumplings can be cooked straight from frozen without thawing.
