Tip: To garnish this drink, thread fresh cranberries and fresh lemon slices onto wooden skewers.
Combine the sparkling water and cranberry-raspberry drink in a pitcher; stir well. Spoon 1 tablespoon crème de cassis in each of 6 glasses; add 1 cup juice mixture.
Note: For a nonalcoholic version, omit the crème de cassis--the recipe works fine without it.
