I think creating a different crust and perhaps folding in some type of liqueur into the sour cream topping will add some pazzaz.( I would suggest using creme fraiche) Construct the crust by adding the following into a food processor:1/2 bag of Skor toffee bits,toasted pecans, 1/4 tsp cinnamon,8- 10 shortbread cookies, and 2 tsb butter. Press into springform pan- bake 10-15 min until golden brown- let set for 30 min. Add cheesecake recipe- follow your recipe - then fold 1 tsb of amaretto or liqueur of your choice to sour cream/ creme fraiche topping. Once cheesecake is set spinkle toffee and chopped toasted pecans around the sides of the cheese cake. whatever you choose- Good luck-
