1 cup Ceres guava juice blend
1 cup Brown Cow vanilla yogurt
1/2 cup Season's Choice tropical blend frozen fruit (pineapple, mango, papaya, strawberry)
1 1/2 teaspoons acai berry powder
1/2 cup ice
This one is barely thicker than juice, with a faint lavender color. The flavor is vaguely tropical. I think the general concept would work better with goji berry instead of acai berry.
