Crust: Toss the cookies crumbs and the butter in a large bowl until well coated. Butter and flour a 10 inch pie pan. Using your hands, press the crumb mixture onto the bottom and sides of the pan. The bottom, sides and edge of the crust should be ¼ inch thick. Using your fingers, flatten the edge flush with the top of the pan. Freeze for 30 minutes. Spread the melted chocolate over the cold crust and refrigerate for 20-30 minutes to set before using.
Method: Preheat the oven to 325 F. Bake the crust for 7-8 minutes or until the bottom feels crisp. Cool in the pan for 10 minutes then transfer to a rack to cool completely. To make the filling, heat the milk in the top of a double boiler set over simmering water until bubbles appear. Do not allow the milk to boil. Add about one – fourth of the marshmallows and stir until melted. Add the sour cream and stir until thick and creamy. Remove from the heat and stir in the liqueurs and food coloring. Stir until fluffy integrated. Pour the filling into the crust, cover the plastic wrap, and freeze for 2-3 hours, or until firm. Remove from the freezer 30 minutes before serving. Spoon the whipped cream into a pastry bag fitted with a large star shaped tip. Pipe seven mounds of cream in a ring around the border of the pie, just inside the crust, and a large mound in the center. Top each mound with a maraschino cherry. Place the marzipan decorations in between the mounds of cream.
