Rinse very well the rice and cook it in two cups (500 ml) water. The rice does not need to be very soft, it is ok if it’s still slightly hard.
Drain the water from the rice and let it cool for 30 minutes.
Transfer the rice to a food processor. Add dates and 3,5 cups water. Process again for 15-20 seconds until smooth. The mixture should resemble a very thin puree.
Pass it through a fine mesh sieve or a cheese cloth. It will take some time to do this but the texture of the milk will be much better.
Notes
Instead of dates you can use maple syrup, stevia or other natural sweetener of choice.
