In a medium bowl, mix together the melted butter, graham cracker crumbs, sugar, salt, cayenne pepper, and caramel sauce until well combined. Press the mixture into the bottom of an 9-inch springform pan. Bake for 10 minutes, then cool.
In a large bowl, beat together the cream cheese and sugar until smooth and creamy. Beat in the sour cream, bourbon, flour, and salt until well combined.
Add the eggs, one at a time, beating well after each addition. Fold in the caramel sauce and pour the mixture over the cooled crust.
Bake for 1 hour or until the edges are set and the center is slightly jiggly. Turn off the oven and let the cheesecake cool in the oven for 1 hour before removing.
While the cheesecake is cooling, make the candied pecans topping. In a small saucepan, cook the pecans, sugar, and salt over medium heat until the sugar has melted and the pecans are coated and fragrant. Spread the pecans onto a piece of parchment paper to cool.
Once the cheesecake is completely cooled, refrigerate for at least 2 hours or overnight. When ready to serve, remove from the pan and top with the candied pecans. Enjoy!
