Steps

1. To make the dipping sauce: Combine soy sauce, rice vinegar, chives, sesame seeds, and chile-garlic sauce in a small bowl. Set aside.
2. To make the dumplings: Mix pork, garlic, egg, chives, soy sauce, sesame oil, and ginger in a large bowl until thoroughly combined.
3. Place a dumpling wrapper on a lightly floured work surface and spoon about 1 tablespoon of filling in the middle.
4. Wet the edge with a little water and crimp together forming small pleats to seal the dumpling. Repeat to form remaining dumplings.
5. Heat 1 to 2 tablespoons vegetable oil in a large skillet over medium-high heat. Place 8 to 10 dumplings in the pan and cook until browned, about 2 minutes per side.
6. Pour in 1 cup of water; cover and cook until dumplings are tender and pork is cooked through, about 5 minutes.
7. Repeat to cook remaining dumplings, adding more oil and water for each batch.
8. Serve dumplings with dipping sauce.
