Mix rice flour, cinnamon stick and almond milk in a blender or food processor until cinnamon is completely pulverized. Pour into a small pot and warm over medium-high heat until it starts to boil. Add vanilla extract, turn the heat off and set aside.

In a food processor or blender, combine strawberries (remember to leave a few extra for garnishing), condensed milk and one cup of water. Mix until well integrated and as smooth as possible.

Strain rice flour mixture into the water, pour the strawberry-condensed milk mixture and mix well. Adjust for sweetness.

Either cut in half or chop strawberries to garnish the glasses. Chill or pour over ice and serve.
