First process the ice cubes into snow in the blender, then add the cherries and mix again. Last but not least, add the yogurt (always use the lactose-free one) and puree again. If you can see a wonderful pink liquid in the blender, pour it into two glasses and enjoy!
I often dip the edge of the glasses in lemon juice and then in sugar (looks so pretty) and serve the whole thing with a straw.
