Blend flour with 1/2 cup buttermilk until smooth. Add beaten eggs to sugar and butter. Add 1-1/2 cups buttermilk and vanilla. Add buttermilk-flour mixture. Mix all ingredients thoroughly and pour into unbaked pie shell. Bake in 350 degree oven for 40 to 45 minutes. This pie will rise high but will sink when taken from the oven. Coconut sprinkled over pie gives a pretty finish. This is an old recipe, inexpensive but delicious. From . Downloaded from G Internet, G Internet.
