Rachel's Coconut Horchata

Blend 2 cups skim milk rice and cinnamon sticks in a blender on low speed until rice and cinnamon are slightly chopped. Increase speed to high and blend until rice is very small and cinnamon sticks are crushed 2 to 3 minutes. Pour rice mixture into a sealable container and cover tightly. Refrigerate for 24 hours.

Strain rice mixture through a fine sieve into a bowl. Discard rice and cinnamon sticks. Stir remaining 6 1/2 cups milk coconut milk sugar and vanilla extract into rice mixture until sugar is dissolved. Refrigerate until chilled.
