"Smartie" Juice

I ran into this one last night when trying to make vegan blueberry yogurt. It tastes like liquid Smarties!

Put in a blender:
1 cup frozen blueberries
Fill to 8 oz line with rice milk
Add the juice of 1/2 lemon
Fill to 16 oz line with water
Blend.

I think if you don't use water the blueberries cause the rice milk to congeal into a yogurt like mix.

Post script: It turns out that the blueberry juice is what makes it taste like smarties: it's made of grape juice, pommegranite juice, blueberry juice and (?) apple juice.
