Start by gathering all your ingredients. In a food processor, combine the ground chicken, celery, carrots, soy sauce, fresh ginger, garlic, and sesame oil. Pulse until the mixture is well combined but still has some texture. This filling should be flavorful and aromatic.
Next, bring a large pot of water to a boil. This will be used to cook the dumplings. It's essential to have the water boiling hot to ensure the dumplings cook evenly.
Now, take a wonton wrapper and place it on a clean surface. Be sure to keep the rest covered with a damp cloth to prevent them from drying out. This is a crucial step to ensure your wrappers remain pliable.
Using a spoon, scoop a heaping teaspoon of the filling mixture and place it close to one of the corners of the wonton wrapper. Make sure not to overfill, as this can make sealing difficult.
Dip your finger into the bowl of water and moisten the edges of the wonton wrapper. This helps create a seal when you fold it.
Fold the edge of the wonton wrapper over the filling to form a triangle shape. Press the edges firmly to seal, ensuring no air is trapped inside. You want to achieve a tight seal to prevent the filling from leaking out during cooking.
If you're feeling adventurous, you can create a more intricate shape by moistening the center of the wonton and folding in the two opposite corners. This gives the dumpling a delightful presentation.
Once you have your dumplings ready, carefully drop about five into the boiling water at a time. Cook them for about two minutes. You’ll notice they will float to the top once they are done.
Using a slotted spoon, remove the dumplings from the water and place them on a plate. Allow them to cool slightly before serving. Repeat the process with the remaining dumplings.
