Swirled Chocolate Marshmallow Pie

In a small bowl, combine the flour, sugar and salt; cut in butter until crumbly. Whisk cream and egg yolk; gradually add to flour mixture, tossing with a fork until dough forms a ball. Wrap in plastic. Refrigerate for 1 hour or until easy to handle.
Roll out pastry to fit a 9-in. pie plate. Transfer to pie plate. Trim pastry to 1/2 in. beyond edge of plate; flute edges. Line unpricked pastry with a double thickness of heavy-duty foil. Fill with dried beans, uncooked rice or pie weights.
Bake at 400u0b0 for 20 minutes. Remove foil and weights; bake 8-10 minutes longer or until golden brown. Cool on a wire rack.
In a microwave, melt chocolate chips; stir until smooth. Brush over the bottom and up the sides of pastry shell. Refrigerate.
Meanwhile, dissolve cocoa in boiling water; set aside. In a large metal bowl, sprinkle gelatin over 1/3 cup cold water; set aside. In a large heavy saucepan, combine the sugar, corn syrup, honey and remaining water. Bring to a boil, stirring occasionally. Cook, without stirring, until a candy thermometer reads 240u0b0 (soft-ball stage).
Remove from the heat and gradually add to gelatin. Beat on high speed until mixture is thick and the volume is doubled, about 6 minutes. Carefully fold in dissolved cocoa, creating a swirled effect. Pour into prepared pastry. Cover and cool at room temperature for 2 hours.
