Buttermilk pie

Buttermilk pie is a traditional custard-like pie of the southern United States. The basic filling consists of a mixture of eggs, sugar, buttermilk, dry biscuit mix, and butter; variations on the recipe may include flavorings such as lemon zest. Buttermilk pies may be made with or without a pastry crust. The liquid filling is poured into a pie pan (into a crust if one is used) and baked until the mixture sets. It is related to chess pie and pecan pie. The pie may be eaten either while still warm from the oven or after being chilled.
