Gingersnap-Pear Cheesecake

Heat oven to 350° F.

In a medium bowl, combine the butter and crushed gingersnaps. Press the mixture into a 9-inch springform pan, working the crumbs over the bottom and then up the sides. Bake for 20 minutes.

In a small bowl, toss the pears and ginger. Line the cooled crust with the pears, overlapping the slices slightly.

In a large bowl, with an electric mixer on medium, beat the cream cheese for 2 minutes. Add 1 cup of the sugar and beat for 2 minutes. Add the eggs, 1 at a time, and mix until combined. Stir in 2 teaspoons of the vanilla. Pour the mixture over the pears. Bake until the top is barely set but still slightly wobbly, about 50 minutes. Transfer pan to a wire rack but leave oven on.

In a small bowl, combine the sour cream and the remaining sugar and vanilla. Pour over the cheesecake and bake for 8 minutes. Transfer to a wire rack and cool to room temperature. Cover and refrigerate for at least 4 hours before serving.

In Advance: Make the cheesecake and refrigerate for up to 2 days. Slice it just before serving, running the knife under warm water after each cut.
