How to Make It
Preheat the oven to 350°. In a food processor, pulse the gingersnaps with the walnuts until finely ground. Add the melted butter and pulse until the crumbs are moistened. Press the crumbs evenly into a 9-inch glass or ceramic pie plate.
In a medium bowl, whisk the pumpkin with the brown sugar, honey, ground ginger, cinnamon, salt, ground cloves, eggs and heavy cream. Pour the pie filling into the crust. Bake for 35 to 40 minutes, until the crust is deep brown and the filling is just set around the edges but still slightly jiggly in the center; cover the edge of the crust with strips of foil halfway through baking to prevent burning. Transfer the pie to a wire rack to cool.
In a medium saucepan, combine the orange juice with the water, granulated sugar and flour and whisk until smooth. Add the cranberries and cook over moderate heat, stirring, until the liquid is thickened and glossy and the cranberries just begin to burst, about 5 minutes. Carefully pour the hot cranberry glaze over the pie and refrigerate until well chilled. Sprinkle the walnuts on top of the pie just before serving.
