Add cold water; measure 3/4 cup into small bowl. Refrigerate remaining gelatin until slightly thickened. Stir in fruit; pour into serving bowl. Refrigerate until set but not firm.
Meanwhile, place small bowl of measured gelatin in larger bowl of ice water; stir until slightly thickened. Beat with mixer on high speed until thickened and about doubled in volume. Spoon over gelatin in bowl.
