Place thawed berries in a blender container. Cover; blend until smooth. Strain to remove seeds. Stir in the 1/4 cup sugar. Set aside. In a 1-cup heat-safe measure combine orange juice or liqueur and gelatin; let stand 5 minutes. Place measure in a saucepan filled with 1 inch of water. Heat until gelatin dissolves, stirring constantly. Beat whipping cream and 3 tablespoons sugar to soft peaks. Gradually add gelatin mixture, beating to stiff peaks. Reserve 3-1/2 cups of the whipped cream. To remaining whipped cream, fold in berry puree and 2 cups of the fresh berries.
