Mix the white sugar, brown sugar, salt, corn syrup, butter, eggs, bourbon (optional) and vanilla together in a bowl. Arrange the pecans in the bottom of the unbaked pie shell.
Pour the syrup mixture over the top. Bake the pie until it's no longer loose and jiggly, 1 hour 10 minutes, being careful not to burn pecans and crust. (Cover with foil for part of the baking time if it browns too quickly).
Allow to cool for several hours or overnight. Serve in thin slivers with freshly whipped cream.
