1/2 cup butter or margarine
2 cups sugar
3 eggs
2 teaspoons vanilla
3 tablespoons all-purpose flour
1/4 teaspoon salt
1 cup buttermilk
1/2 cup chopped pecans
1 9-inch pie crust, unbaked

Cream butter or margarine and sugar together, adding sugar gradually. Add eggs one at a time. Blend in vanilla, flour and salt. Add buttermilk and mix gently. Sprinkle pecans in pie crust and pour custard mixture over pecans. (Pecans will come to the top as the pie bakes). Bake in a 300 degree F oven for 1 1/2 hours. Test by inserting a knife in center of pie.
