2/3 cup boiling water
1 small box orange gelatin
1/2 cup cold water
Ice cubes
1 (8 ounce) container Cool Whip
6 ounces shortbread crust
Cool Whip (for garnish)
Orange slices (for garnish)

Stir boiling water into gelatin in large bowl for 2 minutes or until dissolved.

Mix cold water and ice to make 1 1/4 cups. Gradually add to gelatin, stirring until slightly thickened (consistency of unbeaten egg whites). Remove any remaining ice.

Stir in the container of Cool Whip with a wire whisk until smooth. Refrigerate 10 to 15 minutes or until mixture is very thick and will mound. Spoon into crust. (There is likely to be some left over.) Refrigerate 3 hours or until firm.

Decorate top of pie with Cool Whip and orange slices just before serving.
