Blind bake tart shell for 10 minutes in a preheated 350 degree oven. In a mixing bowl, combine ingredients thoroughly. Pour sweet potato mixture into tart shell and return to 350 degree oven and bake for 25 minutes or until center is set.
Pastry Dough Recipe:
In a food processor, combine the flour, butter and salt and pulse until the mixture is very coarse. Pour the flour/butter into a large bowl and add the ice water. Pour out onto a clean, flat surface into a large log. Using the palm of your hand, gently push and pull the mixture to form it into a dough. Do not knead, you are just slightly manipulating it.
