Dumplings are delicious, but the filling is tricky to mix. First, it's physically demanding, time-consuming, and labor-intensive. Second, it's a matter of technique; if not mixed properly, the meat filling can release water, causing the dumplings to break their skins during cooking. But in reality, you can solve both of these problems by simply adding some potato mash when mixing the filling.
First, prepare a small potato, wash and peel it, then steam it until cooked. After it has cooled slightly, chop it into small, rice-sized pieces. Finally, add the potato mash along with seasonings like chopped scallions, ginger, garlic, cooking wine, and salt into the container with the meat filling. Stir in one direction. You'll find that in no time, the filling becomes thick and sticky, saving both time and effort.
The filling prepared this way allows the potato to absorb the meat juices and vegetable broth, minimizing nutrient loss. Moreover, this method isn't just for dumpling filling; it can be used for other stuffed foods as well.
