"A refreshing Mexican drink made with rice, milk, vanilla, and cinnamon. A great balance for spicy foods, enjoy this served over ice."
Ingredients:
1 cup uncooked white long-grain rice
5 cups water
1/2 cup milk
1/2 tablespoon vanilla extract
1/2 tablespoon ground cinnamon
2/3 cup white sugar
Directions:
1. Pour the rice and water into the bowl of a blender; blend until the rice just begins to break up, about 1 minute. Let rice and water stand at room temperature for a minimum of 3 hours. 2. Strain the rice water into a pitcher and discard the rice. Stir the milk, vanilla, cinnamon, and sugar into the rice water. Chill and stir before serving over ice.
