4 cups cherries (1 1/2 to 2 pounds), washed
12 ounces frozen limeade
1 tray of ice cubes
1 cup sparkling water
Together, you and your child can stem and pit the cherries.
In a blender, purée the cherries with limeade and ice cubes until smooth. Transfer to a bowl, then stir in sparkling water.
Spoon mixture into 5-ounce paper cups and freeze until firm but not solid, about 2 hours, stirring occasionally.
