Buttermilk Pie

My Aunt Noopy used to make this when I was little. She would make 5 or 6 of them at time. She passed away a long time ago so I havent had it in a while. So the last time I made one, it was just as good as I remembered.

1 unbaked 9 inch deep dish pie shell.
1 1/2 cup of sugar
1 tbsp flour
1 tbsp lemon zest
1 tsp pure vanilla extract
4 eggs
1 cup buttermilk
1 stick of melted butter.

Preheat oven to 350* Mix all the ingredients together in a large bowl. Pour mixture in the pie shell and bake for 25 minutes. Enjoy the goodness.
