In a medium bowl combine the flour and salt.

Cut the cold butter into cubes and toss in the flour.

Using your fingers, cut the butter into the dry ingredients until quarter sized pieces are left.

Add the vodka (optional) and a small amount of water, then toss with your hands to combine. Continue adding very small amounts of water until the dough can hold together, but is not overly wet.

Wrap the dough tightly in plastic wrap, then chill for one hour.

On a lightly floured surface, roll the dough out into a rough rectangle, fold in half, then again into quarters. Wrap the dough in plastic wrap and chill for another 30 minutes.

Roll the dough out again into a rough rectangle and repeat the folding process. Shape the dough into a disk, wrap tightly in plastic wrap, and chill overnight.

Roll out the pie dough into a rough circle about ⅛″ in thickness.

Carefully place the dough in the pie pan, pressing up against the sides. Cover and chill in the fridge for about 20 minutes.

Take the pie crust out, cut off the excess dough, and crimp the edges as desired. Dock the bottom and sides of the crust all over with the tines of a fork, then chill for another 20-30 minutes.

Meanwhile, place a baking sheet in the oven and preheat it to 425 degrees F.

Place a large piece of parchment paper over the pie crust and fill with pie weights, dry beans, or dry rice all the way up to the crimp.

Place the pie pan on the hot baking sheet and bake for 18 minutes.

Take the pan out, take all of the pie weights out, then brush the pie crust with an egg wash all over, except for the crimp.

Bake for an additional 3-5 minutes or until barely golden. Allow the pie crust to cool completely before adding the pie filling.

Turn the oven down to 325 degrees F.

In a small saucepan, combine the butter, chocolate, cocoa powder, espresso powder, salt, and milk. Place over low-medium heat and stir often until fully melted and smooth. Set aside to cool.

In a large mixing bowl, add the sugars, cornmeal, eggs, and vanilla. Use an electric hand mixer to beat until lighter in color and doubled in size.

Drizzle in the dark chocolate mixture, and mix until fully combined.

Pour the filling into the cooled crust, then place on a baking sheet. Wrap aluminum foil around the crimp to prevent it from getting too dark. Bake the pie for 1 hour to 1 hour 15 minutes until set and slightly puffed up.

Allow the pie to cool for at least 2 hours before serving.
