Heat 1/2 cup of cooking oil when the pan is hot. Pour hot oil out and set aside to be used later.
Place the dumplings into the pan, as close together as possible.
Pour water into the pan and stop when it is 1/3 to 1/2 full with water.
Bring to a boil.
Cover the pan and wait till the water has evaporated. Do not be tempted to open. You can hear it has no more water.
Open the lid and pour the reserved 1/2 cup of oil onto the pan to brown the bottom.
Once lightly browned, remove from the pan, and sprinkle sesame seeds, chopped spring onions, chives or cracked black pepper.
Serve immediately.
