This is a very pretty salad, and looks great when prepared and served in the Pampered Chef Trifle Bowl.
4 cup boiling water
1 pkg (8-serving size) Jell-O Berry Blue gelatin
1 pkg (8-serving size) Jell-O Strawberry gelatin
2 cups cold water
1 cup blueberries
1 tub (12 oz) Cool Whip
1 cup strawberries, sliced
Stir 2 cups of the boiling water into each flavor of dry gelatin mix in separate medium bowls and stir for 2 minutes or until gelatin is dissolved. Stir 1 cup cold water into gelatin in each bowl. Refrigerate blue gelatin for 1 1/2 hours or until thickened (spoon drawn through leaves definite impression). Let Strawberry gelatin stand at room temperature.
Add blueberries to thickened blue gelatin; stir. Pour into 4 - 6 quart glass bowl. Refrigerate 30 minutes or until set, but not firm (gelatin should stick to finger when touched.) Spread with 3 1/2 cups of the whipped topping; refrigerate. Meanwhile, refrigerate strawberry gelatin 1/12 hours or until thickened. Stir in strawberries; spoon over whipped topping layer.
Refrigerate 3 hours or until firm. Top with remaining whipped topping. Store in refrigerator.
