2 ripe mangoes (about 3/4 pound each) or 1 mango and 1 banana
2 pieces crystallized ginger, about 1 ounce
1 cup low-fat buttermilk
One 8 oz. container low-fat vanilla yogurt
Handful of chipped ice
To cut mango into pieces, stand it on end and slice the flesh off both sides of the central pit.
Lay each half on a cutting board, and with the tip of your knife, score the flesh in a cross-hatch pattern. Pushing from the skin side, turn inside out so that the mango flesh pops up; slice it off the skin. Also cut off the remaining flesh from around the pit and remove the skin.
In a blender, puree the fruit and ginger, scraping down the sides as necessary. Add the buttermilk, yogurt and ice and purée until smooth and frothy. Pour into glasses.
