Buttermilk Pie

9 in. frozen pie crust
3 3/4 cups sugar
1/2 cup flour
6 eggs
1 cup buttermilk
1 tsp. vanilla
1/2 tsp. salt
2 sticks melted butter

Mix flour, salt, and sugar and set aside. Beat eggs with a fork or whisk to mix them together. Add buttermilk, your flour mixture, and vanilla to the eggs. Then stir in the butter. Pour into pie crust. Bake at 350 deg. for 50 minutes to 1 hour. It should be golden brown--shake it a tad to make sure center is jiggly, but not liquidy.
This recipe came from my mother-in-law. John is usually the one that makes this for holidays. He has told me several times that it's his favorite dessert.
