- Sweet potato pie is a traditional dessert popular in the Southern United States. It is often served during the American holiday season, especially at Thanksgiving, and is similar in many ways to pumpkin pie.
It is usually made as a large tart in an open pie shell without a top crust. The filling consists of mashed sweet potatoes, milk, sugar and eggs, flavored with spices such as cinnamon and nutmeg. Other possible ingredients include vanilla or lemon flavoring, maple syrup, molasses, and brown sugar. The baked custard filling may vary from a light and silky to dense, depending on the recipe’s ratio of mashed potato, milk and eggs.
