Atole de Arroz (Mexican Rice Atole)

Steps

1. Rinse rice under cold water until water runs clear.
2. Place rice, water, and cinnamon stick in a medium-large pot. Bring to a boil over medium-high heat, then reduce heat to low and simmer 20 minutes, stirring occasionally.
3. Add milk and sugar, stir to combine, then remove half of the cooked rice from the pot.
4. Blend the removed rice until smooth.
5. Return the blended rice to the pot and cook over medium-high heat until it boils again and thickens slightly.
6. Remove the cinnamon stick and serve in mugs, dusting with ground cinnamon if desired.
