Preheat oven to 425 degrees F.
For the crust: Put the graham crackers in a food processor and process until all the pieces are broken down to a sand-like consistency. Add the nuts and process until they are completely combined with the graham crackers. With the processor on, pour the butter in a slow steady stream, until the mixture looks bound together. Press the crust evenly into the bottom and a little up the sides of a 9-inch springform pan. Set aside.
For the filling: In a large bowl, mix together; cream cheese, sugar, eggs, and yolks. Add cinnamon, flour, cloves, and ginger. Blend together. Add cream and vanilla, and blend well. At this point, reserve 1/4 cup of the mixture. Add the pumpkin and blend until the color is even.
Pour the pumpkin filling into the prepared crust. Take the reserved mixture and create a design on top; a swirl, or pour thin lines across, from top to bottom, then take a knife and working perpendicular to the lines of white filling, run the knife through in similarly spaced lines.
Place on the middle rack of the oven and bake for 15 minutes. Reduce temperature to 275 degrees F and bake for 1 more hour. Cool, then chill in the fridge overnight.
Serve with brandied whipped cream.
