Combine gelatin, 1 tbsp. sugar, and salt in saucepan. Beat egg yolk slightly. Add egg yolks, cream and whiskey to gelatin mixture. Cook over low heat, stirring constantly, until mixture thickens slightly. Stir in mint jelly. Chill until mixture begins to thicken. Beat egg whites to soft peaks. Beat in remaining sugar until mixture holds a stiff peak. Fold meringue and 2 cups whipped topping into custard mixture. Add green food coloring to desired shade. Turn into crust. Garnish with remaining whipped topping and refrigerate until firm. Let stand at room temperature for 2 hours before cutting.
