This can also be made without the bourbon but it IS better with it. This cheesecake is very light and fluffy and not dense it has an extreme flavor, you will get many rave reviews when you serve this at your next dinner. When serving on plate drizzle with caramel sauce or a dollop of whipped cream. This is an outstanding and easy to make cheesecake, one you will be proud to serve. If you like an extreme spice flavor increase the cinnamon, nutmeg and ginger by 1/2 teaspoon. Just a hint... If you don't want to purchase a full bottle of bourbon, just purchase those little small about 1/3-cup bottles, the kind that they serve on airplanes, anywhere that wine or whiskey is sold, and use it for this recipe, it really kicks up the flavor big time! Plan ahead or a day before this cheesecake needs to chill for a minimum of 6 hours or overnight. I lightly drizzle my caramel sauce over the cheesecake slices (recipe#78088) when serving on plates, or dollup with whipped cream.
