Place the shiratamako, joshinko, and sugar in a large bowl.
Gradually add silken tofu (or water), stirring with a wooden spatula until it all comes together to form a dough.
Divide the dough into three equal portions.
Add the matcha powder (or alternative coloring) into one of the dough portions and knead until the dough turns green.
Add 1/2 tps of sakura cherry blossom powder (or alternative coloring) into one of the other dough portions and knead into the dough until it turns light pink.
Roll each ball of dough (green, pink, and white) into 6 uniform-sized balls.
Boil a pot of water and add the dango balls.
Once the dango floats to the surface of the water leave them cooking for a few minutes more, then scoop them out and put them into a bowl of ice water to stop the cooking process.
Place one green dango, one white dango, and one pink dango onto a skewer and repeat until all the dango are skewered then serve!
Notes
Substitutions: If you don’t have tofu, you can replace it with water. The texture will be slightly different. Flour and water ratio is 1:1
When the dough is cooked, the colour of the dango will be intensified. However, sakura powder does not add much pink colour, so I dropped one drop of red food colouring.
