Fun Bubbly Strawberry Gelatin

1 large box Jell-O strawberry gelatin
1/4 teaspoon salt
2 cups boiling water
1 1/2 cups cold water
1 (10 ounce) package frozen strawberries
1 cup softened vanilla ice cream or sour cream

Dissolve gelatin and salt in boiling water. Add cold water. Measure 2 cups into a separate bowl. Add the frozen fruit. Stir carefully until fruit thaws and separates. Chill until mixture is almost set, about 15 minutes.

Spoon into sherbet or goblet glasses, filling each about 2/3 full. Refrigerate gelatin with glass in a tilted position. Chill until set but not firm. Chill remaining gelatin until slightly thickened. Blend in ice cream. Beat 1 minute or until bubbly. Spoon over gelatin in glasses. Chill until firm about 3 hours.
