Heat the skillet on high heat and add some oil. Let the oil heat for a minute and then turn the heat down to medium. Place the dumplings in the skillet and give it about 1-2 mins to crisp at the bottom. Then add some water to the skillet around the dumplings and cover for 3-5 minutes. Serve with remaining green tea and dipping sauce.
Alternatively, you can even boil water in pot and slide the dumplings in. Cook the dumplings in boiling water on medium heat for 10 mins. Serve with remaining green tea and dipping sauce.
