Sparkling White Grape is a discontinued flavor of Jell-O. It was a very popular flavor up to its discontinuation.
Instructions to Make
1. Stir 3/4 cup boiling water into gelatin in medium bowl at least 2 minutes until completely dissolved.
2. Stir in 1 1/4 cups cold seltzer, club soda or diet ginger ale. (If you use cold water, the gelatin will not have a sparkling fizz.)
