First, make the dumplings. Place the shiratamako flour into a bowl, and gradually drizzle in the water. Knead with a spoon (or your hands – much easier). The dough should form into one piece, and be firm enough for a piece of dough to be rolled into a ball, and retain its form when placed down. Depending on the humidity of your house, you may need to add a bit more flour or water, but do so very gradually.
Dye the dough red with some food coloring.
Roll the dough into little balls, then flatten them with your finger to create red blood cell shapes!
Place the dumplings in a pot of boiling water. Once they have risen to the surface, boil for 1 minute, then place in a bowl of ice water. Then place them on a plate lined with saran wrap while you make the syrup.
Place the coconut milk, brown sugar and raspberries into a pan and bring to a boil. Add some red food coloring to make it look like blood. Pour this through a cheesecloth to remove the raspberry seeds.
Spoon the red blood cells into a bowl, then pour the blood syrup on top. Enjoy!
