Water Pie Custard Vanilla Crust

Featured in: Sweet Treats

Water pie is a nostalgic American dessert dating to the Great Depression era, relying on simple pantry staples like water, sugar, flour, and butter. Its creamy, custard-like filling develops a rich vanilla flavor, perfectly complemented by a crisp, golden pie crust. Preparation involves layering water in an unbaked crust, topping with sugar-flour blend, vanilla, and butter, then baking until set. For extra aroma, spice it with cinnamon or nutmeg, or serve with berries and whipped cream. Cooling and refrigeration are key for best texture, resulting in gentle slices ideal for any occasion.
