Notes
Cinnamon sticks are truly best. However, if you don't have those, substitute ½ teaspoons of ground cinnamon for every 5 cinnamon sticks. You can leave the rice and water in the blender overnight. This will reduce the number of dishes you need to do. It will also let you pulse the rice and water mix just before you strain it, which helps improve the texture and flavor. If you are pressed for time, you can cut the resting time down to 3 hours.Nutritional information is provided as a courtesy only and should be considered as an estimate rather than a guarantee.
