Preheat oven to 350°F (175°C). Wrap the bottom of a 9-inch springform pan with aluminum foil.
In a medium bowl, combine graham cracker crumbs, sugar, melted butter, ground ginger, and cinnamon. Press the mixture evenly into the bottom of the prepared springform pan.
Bake the crust for 8-10 minutes. Remove from oven and let it cool slightly.
In a large bowl, beat cream cheese and sugar until smooth. Beat in flour.
Beat in vanilla extract, cinnamon, and nutmeg.
Add eggs one at a time, beating well after each addition.
Stir in sour cream until just combined.
Pour the filling over the cooled crust.
Bake in a water bath for 50-60 minutes, or until the center is almost set. Turn off the oven and let the cheesecake cool in the oven with the door ajar for 1 hour.
Remove from oven and cool completely on a wire rack. Refrigerate for at least 4 hours, or preferably overnight.
Notes
Garnish with whipped cream, a sprinkle of cinnamon, or fresh cranberries for an extra festive touch.
