Preheat oven to 450 degrees.
In a large mixing bowl combine flour, sugar, cinnamon, nutmeg, vanilla, salt, water, and milk. Pour mixture into unbaked pie shell. NOTE: Don't over fill pie shell. If you have extra mixture, place into oven proof ramekins and bake next to pie.
Place 5 pats of butter on top of mixture in pie shell.
Bake in preheated oven for 15 minutes. Reduce oven temperature to 350 degrees and bake an additional 45-50 minutes. Pie will be loose. It will firm up once cooled and chilled.
Remove from oven and let sit until cooled completely. Place in refrigerator for a couple of hours to help set up pie. NOTE: pie will have a custard like consistency. Enjoy.
