Go back in time with this depression era Water Pie made famous again by Dylan Hollis and Paula Deen. A vintage southern style pie first thought of during hard times.
Preheat oven to 350° F. Grate butter and place in the freezer.
Grease 9" pie plate or line with parchment paper. Place pie crust into bottom and up the sides of the pie plate.
Sift flour, sugar and salt together in a small bowl. Pour water into the pie crust. Sprinkle flour mixture evenly over top of the water. Pour vanilla evenly over the top. Remove butter from the freezer and spread evenly over the top. See process pictures above for a visual, if desired.
Bake for 25 minutes. Remove from oven and cover edges with aluminum foil. The easiest way for me to do this is to cover the entire pie with foil, then make some cuts in the center and peel the foil back (see photo above). Bake an additional 35 minutes. The pie should be bubbly and look like it's turning slightly golden in some places.
Allow to cool completely to room temperature, then refrigerate 2-24 hours before serving.
Notes
This pie crust will stick to the pie plate. Please make sure to grease your pie plate or line it with parchment paper.
Place grated butter in the freezer while assembling the rest of the pie. It makes it much easier to work with.
Make sure you allow it to cool to room temperature before placing in the refrigerator or it won't set up properly.
After cooling to room temperature, make sure to refrigerate a minimum of 2 hours so that it sets up properly.
There will be just a tiny bit of water on the top of the pie when it is completely set up, this is normal.
