Preheat oven to 450 degrees. In a large non-metal bowl combine sugars and eggs. Add in the pumpkin mush, the spices, salt, and evaporated milk. Pour the filling into the pie shell. Bake for 10 minutes, then reduce heat to 350 and bake for another 50 minutes, or until pie sets.
Makes 6-8 servings.
*Pumpkin mush: cut a medium pumpkin in half. Prick the skin several times with a fork, and place on a cookie sheet, cut-side up. Bake for 50 minutes or until very soft when poked with a fork. Let the pumpkin cool, then scoop out the seeds with a spoon. Scoop out the pumpkin meat, and throw away the skin. Mash the pumpkin meat with a potato masher or puree in a blender/food processor. Makes about 4 cups.
