Place graham cracker crumbs and ground cinnamon in a medium sized mixing bowl and mix together thoroughly with a rubber spatula. Add powdered sugar and mix thoroughly. Add melted butter and mix well.  Prepare a 9-inch round cake pan by cutting a round piece of parchment paper, grease the bottom of the pan and the sides with a nonstick baking spray. Place the parchment paper at the bottom of the pan. If using a 9-inch square pan, cut two long strips of parchment paper and place them in the bottom of the pan, creating a sling.

Add the graham crack crumb crust to the bottom of the pan (over the parchment paper), use your fingers creating an even layer of crust across the bottom of the pan. Cover the pan with plastic wrap and chill in the refrigerator for at least one hour.

Heat the oven to 370 degrees F. Add cream cheese to a large mixing bowl. Using an electric hand mixer, beat the cream cheese until smooth. Add eggs and mix until smooth. Add sugar, lemon juice and salt and mix until well combined. Pour the cream cheese filling over the crust in to the pan. Bake for 22 to 25 minutes at 370 degrees F. The cheesecake will be slightly soft in the middle and should be hot all the way through. (If the cake splits, it is over baked).

Remove the cake from the oven and place on a cooling rack. Allow to cool to room temperature, at least one hour.

Add sour cream, sugar and lemon juice to a small glass mixing bowl. Mix together thoroughly with a spoon. Heat the oven to 425 degrees F. Spread the sour cream topping on top of the cheesecake and smooth with a spatula. Bake the cheesecake for another 6 to 8 minutes, just to set the sour cream topping. The cake should not brown at all.

Remove the cake from the oven and allow to cool to room temperature, at least one hour and 15 to 30 minutes. Once it's room temperature, cover with plastic wrap and allow to chill for at least 2 hours (or overnight) in the refrigerator.

Mix sliced strawberries, orange liqueur, orange juice and lemon juice in a glass bowl. Allow to marinate for 5 minutes and then add to a blender.

Serve cheesecake sliced with the strawberry coulis and fresh strawberries.
