Process rice in the jar of a blender until fine crumbs form. Transfer to a medium bowl. Add the water, and stir to combine. Cover with plastic wrap, and place in refrigerator 3 hours or overnight.
Transfer rice and soaking liquid to the jar of a blender; add desired fruit, vanilla, cinnamon, and evaporated milk, if using. Blend on high speed until smooth, about 1 minute; sweeten with honey, if desired. Strain through a sieve into a medium bowl; discard solids. Serve over ice.
I have my own rice recipe drink I've made for years, and I took a look at this one, and decided to try it with cantelope except for the evaporated milk, I use non-fat milk, and taste lighter. well I really recommend this drink-it taste delicious! very refreshing as a summer drink, and kids really like it.
