Instructions

1. In a blender, combine the uncooked rice, cinnamon sticks, and 2 cups of water.
2. Blend on high until the rice and cinnamon sticks are finely ground, creating a thick mixture.
3. Add the remaining 2 cups of water to the blender and blend again for about 30 seconds until well mixed.
4. Place a fine-mesh strainer over a large bowl and pour the rice mixture through the strainer. Use a spoon to press down and extract as much liquid as possible.
5. Discard the rice solids, and transfer the strained horchata to a pitcher.
6. Stir in the sweetened condensed milk until fully combined, adjusting sweetness to taste.
7. Fill two glasses with ice cubes, about halfway.
8. Pour 1/2 cup of cold brew coffee into each glass over the ice.
9. Top each glass with the horchata mixture until filled, stirring gently to combine.
10. Sprinkle ground cinnamon on top for garnish before serving.
