My current recipe is:
50g brown rice
50g almonds
dash of organic sunflower oil
pinch salt
1100g water
 You grind the nuts and rice on speed 9 for about 40 seconds.  Add all other ingredients and cook for 60 degrees, 5 mins, speed 4.  Blend for 40 seconds on speed 8 and strain into a bottle or jug.  Refrigerate.  It's apparently nice hot too.
And that's it - no sweetner.  It's fine like that to use on my muesli etc.  We mainly use cow's milk from our cow, but I still prefer rice milk on cereal and so does one of my daughters.  Handy if we have to cook something dairy-free for guests too.
