Per Chef Adrienne, DO NOT dilute the frozen juice concentrate. "I have made this punch many times and have never diluted the concentrates. The punch is made to be sweet (after all it was for a soap opera human doll child ). There is more than enough ginger ale (a full 2 liter bottle) as well as cranberry juice cocktail (a quart) to handle it all. And after a few generous shots of rum (my preference) you may not care anyway!"
