Step 1

Combine flour and fine salt in a large bowl. Cut in butter with a pastry blender or two knives until mixture resembles coarse crumbs with some pea-sized pieces.

Step 2

Combine water and vodka in a measuring cup and add to flour mixture. Stir to form a shaggy dough. Turn dough out onto a lightly floured surface and bring it together. Wrap in plastic, form into a disk and refrigerate for one hour.

Step 3

On a lightly floured surface, roll pastry into a 33 centimeter round. Place it in a deep 23 centimeter pie plate. Trim and crimp the edges. Refrigerate for 20 minutes.

Step 4

Heat oven to 400°F (205°C).

Step 5

Whisk together filling ingredients in a large bowl. Pour into shell. Bake for ten minutes, then reduce the heat to 350°F (176°C) and continue to bake until the middle is just set, for about 40 minutes - one hour. Tent with foil if pie begins to brown.

Step 6

Transfer pie to wire cooling rack to cool completely. Serve topped with whipped cream and sprinkled with cinnamon.
