Kabocha Squash Pie

Heat oven to 325 degrees. For crust, place walnuts on a baking tray, and toast in oven, stirring once or twice, until fragrant, about 15 minutes. Let cool. Reduce oven temperature to 300 degrees.

In a food processor, combine walnuts with a few tablespoons brown sugar and pulse a few times, until nuts are coarsely ground. In a large bowl, whisk nuts with graham cracker crumbs, remaining brown sugar, lime zest, spices and salt. Pour melted butter over this mixture, and mix with your fingers until butter is distributed. Press evenly into a 10-inch glass pie plate. Bake crust until lightly browned, about 12 minutes, then set aside. Keep oven at 300 degrees.

When squash is cool, cut it in half and scoop out seeds and pulp. Scoop squash flesh into a measuring cup until you have 2½ cups.

In a food processor, process cream cheese with sugar, spices and salt until light and smooth. Scrape down bowl, add squash and process until smooth. Mix in brandy and then eggs, one at a time. Finish mixing with a rubber spatula.

Place pie plate on a baking sheet and scrape filling into crust. Bake until just set in center, about 1 hour. Let cool before serving, topped with crème fraîche and drizzled with butterscotch sauce.
