3 tablespoons flour
1 cup sugar
2 cups buttermilk
¼ cup butter, melted and slightly cooled
3 eggs, separated
Preheat oven to 325°F. Mix flour and sugar together. In a separate bowl, beat yolks until light, and then add to sugar mixture. Add to buttermilk, along with melted butter (slightly cooled so as not to damage eggs).
Beat egg whites until stiff, and then fold gently into buttermilk mixture. Pour all into blind-baked pie shell, then bake for 30 minutes or until the crust is brown and the filling firm. Cool until set enough to slice.
