Here is a Southern Sweet Potato Pie...
3 Medium Sweet Potatos/1 lb baked sweet potatoes
1 pie crust
1/2 C sugar
1/2 Tsp Ground Cinnamon
1/4 Tsp Ground Allspice
1/4 Tsp Ground Nutmeg
1/8 Tsp Salt
3 Slightly beaten eggs
1 C Sour Cream/Buttermilk
Prepare your crust - I prefer a graham cracker, however, the recipe calls for a regular pastry crust. Bake it lightly - you want it cooked.
For filling, scoop out baked potato and mash. Add sugar, cinnamon, allspice, nutmeg, & salt into the potatoes. Add the eggs. Beat lightly either by hand or with a rotary mixer until just combined. Gradually, stir in the sour cream/buttermilk and mix well.
Pour filling into a cooked, cooled crust, smooth out. Bake at 375 F for 25 minutes, with the edges of the crust protected/covered with foil to prevent overbrowning. Remove foil after 25 minutes and continue to bake for another 25-30 minutes or till a knife comes out clean. Cool on rack for 30 minutes and then refrigerate till serving - with whipped cream.
