1 1⁄4 cups (10 1⁄2 ounces or 300 grams, about 1⁄2 to 3⁄4 of a 15-ounce can) pumpkin purée
1⁄4 cup (50 grams) granulated sugar
1⁄4 cup (50 grams) brown sugar

DIRECTIONS
Crust
[1] Preheat your oven to 425 degrees. Remove any children sensitive to loud noises from the premises, and finely grind the gingersnaps and graham crackers in a food processor (yielding 11⁄2 cups).
[2] Add the melted butter, and process until the cookie-crumb mixture is moistened.
[3] Press the mixture firmly into the bottom and up the sides of a 9-inch-diameter tart pan with removable bottom. (I like to use the bottom and outer side of a measuring cup to help pack the crumbs into the base and neatly up the walls of my crumb crusts.)
[4] Place pan on rimmed baking sheet. Cheesecake Batter
[5] Mix together the ingredients in a small bowl until smooth.
Pumpkin Batter
[6] Beat the egg and the egg white lightly in a large bowl.
[7] Whisk in the pumpkin, sugars, salt, cinnamon, ginger, cloves, and nutmeg. Gradually whisk in the cream.
Assemble Tart
[8] Pour the pumpkin batter into gingersnap-graham crust.
[9] Dollop the cheesecake batter over pumpkin batter, then marble the two together decoratively with a knife. Try not to pierce the bottom crust as you do.
[10] Bake for 10 minutes, then reduce temperature to 350 degrees and bake for another 30 to 40 minutes, or until a knife or toothpick inserted into the centre comes out clean.
To Serve
Cool the tart completely on a rack, or in the fridge if you, like me, prefer it cold. Serve immediately, and refrigerate any leftovers. Theoretically, it keeps for several days, but the crumb crust will get a little soft on the bottom after day one.
