After 24 hours, remove the cinnamon sticks from the mixture. Set the cinnamon sticks aside and reuse them as garnish.
Add the following to a blender: 24 hour horchata mixture, chilled sweetened condensed milk, chilled evaporated milk, 16 oz of chilled water and one tablespoon of ground cinnamon. Blend all ingredients on a high speed for approximately 45 seconds to one minute.
Once all items are fully blended, use a mesh strainer to slowly strain the Agua de Horchata mixture into a large pitcher. Discard any of the remaining ground rice and almond that is not filtered by the mesh strainer.
After completing this process, restrain the Agua de Horchata. I do this for good measure and to ensure a smooth and delicious drink.
Once completing the second strain, you are ready to serve the delicious drink. This recipe will yield slightly over six, 10 oz beverages. I hope you enjoy this beautiful Agua de Horchata recipe as much as I do. Serve the agua fresca chilled and on ice. For added flair, lighlty sprinkle ground cinnamon on the top of the drink and garnish with a cinnamon stick.
