1 cup sugar (1/2 brown and 1/2 white)
2 cups sweet potatoes, cooked, peeled, and mashed
3 cups, milk
4 eggs, beaten
1/2 tsp. salt
2 tsp. cinnamon
1 large unbaked pie shell or two smaller ones

Mix above ingredients. Pour stirred ingredients into unbaked pie shell. Cook about an hour at 350°F.

Check for doneness the same way you would check a pumpkin pie. Knife inserted into middle of pie should come out clean, and not gooey.
