Preheat oven to 375ºF. Butter the bottom of a 9-inch springform pan. In a mixing bowl, combine graham cracker crumbs, butter and sugar and mix well. Press onto bottom of springform pan and bake until golden, about 8 minutes. Set aside to cool. When completely cooled, butter the sides of the pan.
Increase oven temperature to 500ºF.
In a large mixing bowl with an electric mixer, combine cream cheese, sugar, zests and vanilla and beat until light and creamy. Add the flour, then the eggs and yolks one at a time, mixing well after each addition. Add the sour cream, vanilla bean seeds and bourbon and mix until smooth. Pour mixture into prepared pan and bake for 12 minutes. Reduce oven temperature to 200ºF and bake for 1 hour more. Transfer cake to a cooling rack and let cool completely. Refrigerate cake overnight before serving.
FOR THE COULIS:
Combine raspberries, sugar, water and orange zest and cook until berries are soft and liquid is syrupy, about 10 minutes. Let cool slightly then puree in a blender. Strain through a fine sieve, transfer to a bowl and refrigerate, covered, until completely chilled. Stir in Grand Marnier and lemon juice and serve alongside OLD-FASHIONED NEW YORK-STYLE CHEESECAKE.
