Place rinsed rice in a large bowl. Fill the bowl with 3 cups of fresh water to cover the rice. Add 2 cinnamon sticks. Cover with a lid and allow to soak overnight in the fridge.
Pour the soaked rice, cinnamon sticks, and water into the blender.
Blend rice until frothy.
Strain the liquid using a metal mesh strainer or cheesecloth.
Add the strained rice milk to a blender. Add plant-based milk, maple syrup, and vanilla extract. Blend the ingredients until frothy.
Transfer to an airtight container and store in the fridge until ready to serve.
Serve over ice with a dash of cinnamon. Enjoy!
Notes
This drink should be smooth and free from grit.
Some small pieces and settling are normal. You may need to stir the drink to redistribute the cinnamon, which tends to settle.
You can use any plant-based milk you like. The recipe was tested with unsweetened vanilla soymilk. The horchata had a smooth and creamy texture.
Store for up to 5 days in a sealed container in the fridge.
