1. Rinse the chia seeds under cold water to remove any impurities.
2. In a bowl, combine the chia seeds and rice milk. Stir well to ensure the seeds are evenly distributed.
3. Let the mixture sit for about 30 minutes, allowing the chia seeds to absorb the rice milk and swell. Stir occasionally to prevent clumping.
4. After 30 minutes, blend the mixture in a blender or food processor until smooth. Adjust the consistency by adding more rice milk if necessary.
5. Pour the blended puree into a serving bowl. You can serve it right away or refrigerate it for later use.
