In a large bowl, mix the flour and 1/2 cup (120 ml) warm water with chopsticks until it clumps. Add the remaining water a little bit at a time and knead the dough with your hand until combined into a big ball. Please note that it is possible that you may need less or more water.
Divide the dough into 20 grams each and roll the ball into balls You should get about 18-19 small balls with about 1-inch diameter.
In a large pot, boil water and add the rice balls. Cook until they float to the top. Scoop them out with a wire ladle and put them immediately into the bowl of the cold water bath to stop the cooking process.
Once they are cooled, drain well and transfer them to a tray. Wet the tray so that the dumplings will not stick.
Skewer three pieces of rice dumplings into a soaked skewer. Continue the rest of the balls and set aside.
Sweet Soy Sauce Glaze

Notes
Dango are best consumed on the same day you make them.
