To Cook the Dumplings and Finish the Stew: 1. Fill a medium pot halfway with salted water and bring to a boil over high heat. Reduce the heat to medium for a steady simmer. 2. Carefully drop the dumplings, a few at a time, into the simmering water. Cook until all of them are floating, about 3 minutes. 4. Use a slotted spoon to scoop the dumplings out of the water and place them on a plate to cool and set slightly, about 3 minutes. 5. Gently stir the dumplings into the stew. Place the stew back over medium heat and simmer for 3 minutes to warm through. 6. Sprinkle with scallions and serve.
