Preheat the oven to 350 degrees F.
In a medium mixing bowl, combine dry crust ingredients. Melt the butter, and mix it in until the mixture is well combined. Press into the base of an 8" or 9" springform pan. Set aside.
In a large mixing bowl, beat the sugar and cream cheese until smooth. Beat in the sour cream, and then beat in the eggs until smooth and well combined. Stir in the salt and vanilla. Pour the filling over the crust.
Set a pan with a bit of water in it on the bottom shelf of your oven, just below where the cheesecake will sit. Place the cake on the rack above the water and bake for 45 minutes to 1 hour, or until the centre of the cake is set (jiggle the pan a little to test it).
Turn off the oven and allow the cake to sit in the oven for 1 hour. Remove from the oven, and refrigerate until cold.
