2 cups cooked brown rice
2 cups hot water
Vanilla, to taste
Brown sugar or maple syrup, to taste
Combine the ingredients in a blender and blend until you can blend no more. Strain through a tight metal strainer and chill.
The first time through, I didn't strain it, but after it chilled, it was a thick slop. After that, I balanced a strainer over a bowl (locking it onto a jug on either side) and poured the mixture into the strainer with extra hot water, scraping out the lumps and extra rice into the sink every once in a while. I ended up with a really great consistency.
