Place all ingredients into the Vitamix container in the order listed and secure the lid. Start the blender on its lowest speed, then quickly increase to its highest speed. Blend for 1 minute 30 seconds or until mixture is very smooth. Pour 3 cups (720ml) of the mixture into ice cube trays and freeze for at least 6 hours until solid. Reserve the remaining liquid in an airtight container and refrigerate. Once ice cubes are completely frozen, remove from trays and let them sit on the counter for 10 minutes. Measure 1.5 cups (360ml) of the reserved liquid into the Vitamix container, then add all the ice cubes. Secure the lid. Start the blender on its lowest speed, then quickly increase to its highest speed, using the tamper to press ingredients toward the blades. Blend for 30-40 seconds or until mixture is processed. In about 30-45 seconds, the sound of the motor will change and four mounds should form. Stop the machine. Do not over mix or melting will occur. Serve immediately.
