1/2 pound seedless red or green grapes
2 cups chilled still water
                    

1. Cut the grapes in half and divide into two equal parts.
Puree half of the grapes with 1/2 cup of the water in a
blender until smooth, for about 30 seconds. 2. Pour the rest
of the water into a pitcher. Strain the pureed grape mixture
through a fine-mesh sieve into the pitcher, and stir well.
3. Place the remaining grape halves in the wells of standard
ice cube trays. Fill the trays with the grape-water mixture
and freeze.
