1 quart plain low-fat yogurt
6 to 8 tablespoons granulated sugar
4 large ice cubes
1 teaspoon ground cardamom
Spoon the plain yogurt into a blender. Add 6 tablespoons of the sugar to the yogurt. Add the ice and cardamom and blend until the yogurt mixture is smooth and frothy. Add up to 2 more tablespoons of sugar if you want a sweeter drink. Pour into tall glasses and serve cold.
