Linda s Coconut Horchata

1 cup uncooked white rice

½ teaspoon ground cinnamon

4 ½ cups water, divided

⅔ cup light coconut milk

⅓ cup superfine sugar

1 teaspoon vanilla extract

Pour rice, cinnamon, and 3 cups water in a blender; blend until rice begins to break up, about 1 minute.

Transfer rice mixture to a large bowl and stir in remaining 1 1/2 cups water; let stand for at least 3 hours, whisking occasionally.

Strain rice mixture with a fine sieve into a large pitcher and discard rice.

Stir coconut milk, sugar, and vanilla extract into the pitcher. Chill completely and stir before serving over ice.
