For Filling
Preheat oven to 375 degrees.
In a saucepot, combine maple syrup and molasses. Bring to a boil and simmer for about 10 minutes. This will be very hot, be careful not to touch the syrup. Remove from heat and quickly whisk in sugar and butter until dissolved and melted.
In a small bowl. whisk together egg, vanilla, salt, cardamom, cinnamon, and nutmeg. Quickly add this to the syrup mix while whisking quickly. Fold in pecans and pour into chilled crust.
Bake for 20 to 30 minutes. The pie will be slightly puffed in the middle and will be set on the sides but slightly jiggly in the center. Allow to cool completely before slicing, preferably overnight. Cut and serve.
