Boil the tapioca
in water until tender and transparent, drain well.
Mix the rice flour with cold water and the salt to
make a thick dough, adding green or red food
coloring.
Bring a saucepan
of water to a simmering boil. Press the rice dough
through the large holes of a grater so that it forms
into droplets. Place in the water to cook until they
float to the surface, cook briefly then retrieve on
a skimmer and transfer to cold water.
In dessert dishes
mix the tapioca and rice beads. Sweeten with sugar
syrup and pour on the two coconut milks, adding
shaved ice to cool the dessert. If liked, add
slivers of fresh fruit.
