Lemon Slushies

1 cup cold water
1 lemon (cut off just the very outer yellow, but leave as much white as possible) cut it in quarters
1/2 cup sugar (or 1/3 cup sugar and 1/3 cup splenda, which is so yummy and less calories)
10-12 ice cubes (depending on the size of your cubes)

Place ingredients in Vita Mix container, or very good blender in order listed. Secure lid, select HIGH, turn to ON. Run about 30 seconds until smooth. Make it pink by adding a few strawberries or raspberries (if the berries are frozen decrease ice a bit.)
