WOW is this one good! I had to jot down the proportions. Cranberries are surprisingly delicious in juice – their tartness is completely balanced out by sweetness from all the other fruit. The easiest way to get ginger juice is to put a chunk of ginger through your juicer, then freeze it in ice cube trays for later.
1/4 pineapple
1 banana
1/2 c. frozen blueberries
1/3 c. cranberries
1 cube of frozen ginger juice
1/2 c water
Dissolve the ginger juice in the water, then pour over the rest of the fruit in a blender.
To add some protein (and ease the glycemic hit of all this fruit), substitute soy milk for the water.
