Combine the rice, cinnamon sticks, and 2 cups of hot water in a bowl with a lid. Allow it to sit for a minimum of 2 hours or overnight if desired.

Once the rice water and cinnamon sticks have soaked for a while, transfer it to a blender. Incorporate 2 additional cups of water and blend on medium until all the ingredients are thoroughly blended.

Separate the rice and cinnamon bits from the mixture by straining.

Ensure that the stems are removed from the strawberries and keep approximately 10 strawberries separate from the rest of the pound.

Add the sweetened condensed milk, whole milk, and vanilla extract to the blender along with the remaining strawberries.

Combine and blend thoroughly, then filter into the rice water mixture.

Stir the strawberry milk mixture and rice water together until thoroughly incorporated, and add an additional cup of water into the mixture.

Cut the remaining 10 strawberries into thin slices.

Combine ice and sliced strawberries in a serving pitcher, then proceed to pour the prepared strawberry horchata into the pitcher.
