24stalks of chives(blanch briefly in pot of boiling water so it's soft enough for you to wrap it around the knot of the dumplings. Cut it shorter if it's too long to wrap one dumpling) - optional
Instructions
Put the beef, onions, garlic, ginger, salt, and soy sauce in a food processor and process to a paste. Transfer the filling to a bowl, cover with plastic wrap, and refrigerate until ready to assemble the dumpings. (The filling can be made up to 24 hours ahead)
Wash and dry the food processor bowl. Place the flour in the food processor and put the lid on. With the processor on, gradually add the water, or as little as 1 3/4 cups. Once there is a ball of dough spinning around inside the processor, turn it off
Turn the dough out onto a lightly floured surface and knead briefly, just to get a feel for the dough. It should be fairly stiff, not too sticky; knead in a little flour if necessary. Set the dough aside, covered with plastic wrap, for at least 30 minutes, or up to 8 hours at room temperature; if longer, the dough should be refrigerated (for up to 2 days, then brought back to room temperature before using)
Prepare the steamer: Use peanut or vegetable oil to lightly oil one large or two smaller bamboo steamer baskets (or use another steaming device that fits over a pot of boiling water)
Cut the dough into 3 equal pieces, then cut each piece into 8 equal pieces. Work with 1 piece at a time, keeping the remaining pieces covered with plastics. On a lightly floured surface, flatten the dough into a disk. With a rolling pin, roll it out until it is approximately 4 inches in diameter
Place 1 level Tbsp of the filling in the middle of the dough, then pick up the edges in several places, gather them together over the filling, and twist and squeeze to seal the top, making a kind of topknot. Place in a steamer basket topknot side up, and continue with the rest to form dumplings
Fill a wok or pot with about 3 inches of hot water, place on a burner, and place a steamer basket over the water; the water should not touch the dumplings. Cover the steamer, bring the water to a boil, and steam the dumpling for 10 to 12 minutes, until the filling and wrappers are cooked through. Serve hot with a bowl of soy sauce and a bit of rice vinegar for dipping, but they are good on their own as well
