Start to boil water in a large pot and prepare a bowl of ice water.
Place the shiratamako in a mixing bowl.
Gradually add water to the bowl while mixing with your hands. Start with about 3/4 of the water and add more as needed.
Knead the dough until it comes together and feels like soft earlobe. It should be pliable but not sticky.
Divide the dough into small, equal portions (about 16-20 pieces) and roll each into a smooth ball about 2cm in diameter.
Gently drop the dango balls into the boiling water. Be careful not to overcrowd the pot.
Cook the dango for about 1-2 minutes. They're ready when they float to the surface.
Scoop out the floating dango and put them into the prepared bowl filled with icy cold water.
Once cooled, drain the dango.
Serve your shiratama dango with your choice of toppings such as anko (sweet red bean paste), kinako (roasted soybean flour), or kuromitsu (black sugar syrup).
Notes
*1 Shiratamako and Glutinous rice flour are both made of sticky rice but the process is different so you can use either but I used shiratamako *2 see the above post for substitution
