To bake a sweet potato pie, start by mixing flour, salt and butter to create the crust. Then roll the crust into a circle and drape it over a pie pan, cutting off the excess that hangs from the sides. Then, in a separate mixing bowl, combine brown sugar, sweet potatoes and spices such as cinnamon, nutmeg and ground ginger. Once done, add the milk and eggs and beat the mixture until well combined. Finally, pour the filling into the crust and bake for 50-60 minutes at 350 degrees Fahrenheit. Keep reading how to roll the pie crust!
