I have been baking the following buttermilk pie for years and it always turned out delightful! In the past year, though, the pie center has been bulging during baking resulting in a delicious, but very ugly pie. Would someone help me remedy this? Here is the recipe: Ingredients ½ cup buttermilk 2 tablespoons all-purpose flour 1 cup white sugar 1/2 cup melted butter (cooled to lukewarm) 3 eggs (beaten) 1 tablespoon vanilla 1/8 tablespoon freshly grated nutmeg 1 (9 inch) unbaked pie crust Directions Preheat oven to 400 degrees. Mix together sugar, flour, and nutmeg; add buttermilk, butter, eggs, and vanilla. Mix well and pour into pie crust. Bake at 400 for 15 minutes. Reduce heat to 325 and bake for approximately 30-40 minutes.
