has to b done in 2-3 batches and mixed together in a large pitcher.
in blender put all the rice , half of the cinnamon, half of the milk some sugar and fill with water and blend on high for 1 minute. Using a metal strainer pour liquid into pitcher avoiding dumping of the rice.
repeat the same steps reusing the rice in the blender and sweeten to your liking. It takes about 2-3 times for me to fill my pitcher.
add ice and serve or chill in refrigerator until ready to serve..
