Equipment

  • 9-inch deep dish pie plate
  • Baking Sheet
  • Foil

Ingredients
 

  • 1 9-inch deep-dish pie crust unbaked
  • 1 1/2 cups water
  • 4 tablespoons all-purpose flour
  • 1 cup sugar
  • 2 teaspoons vanilla extract
  • 5 tablespoons butter cut into 5 pieces

Instructions
 

  • Heat the oven to 400°F and place the empty unbaked pie crust on a rimmed baking sheet. The sheet supports the soft crust and catches any filling that spills while transferring the pie.
  • Pour the 1 1/2 cups water directly into the pie crust. The water should sit quietly in the crust without reaching over the rim.
  • Combine the flour and sugar in a small bowl, then scatter the mixture evenly across the water. Leave the layers untouched so the flour can hydrate gradually and thicken without dense clumps.
  • Drizzle the vanilla extract over the surface and arrange the 5 pieces of butter on top. The butter will float, melt, and form glossy pools across the filling.
  • Bake for 30 minutes at 400°F, then lower the oven temperature to 375°F and continue baking for 30 minutes. Listen for gentle bubbling beneath the butter-slicked top, and shield the crust edge with foil if it browns too quickly.
  • Cool the pie completely, cover it, and refrigerate until thoroughly chilled before slicing. It will look loose and very jiggly when hot, then become much more sliceable as it cools.

Notes

Texture tip: Do not stir the flour, sugar, or butter once added to the water. Leaving the dry mixture untouched allows it to hydrate naturally from below without turning gummy or lumpy.
Slicing tip: Warm a sharp knife under hot water and wipe it dry between cuts so the blade glides smoothly through the chilled custard without tearing the buttery top film.
Storage: Keep leftover pie covered in the refrigerator and serve chilled. Avoid freezing, as thawing causes the delicate gel structure to separate and turn watery.
