Make one nine inch pie
For the crust
1 1/4 cups all-purpose flour
2 teaspoons sugar
1/4 teaspoon salt
1 stick (4 ounces) cold unsalted butter, cut into pieces
1/4 cup ice water
For the filling
2 cups (about 7 ounces) pecans
3 large eggs
3/4 cup dark brown sugar
2/3 cup light corn syrup
1 teaspoon pure vanilla extract
2 tablespoons unsalted butter, melted
3 tablespoons bourbon
1/2 teaspoon salt
3/4 cup semisweet or bittersweet chocolate chips
Making the crust
In a food processor, pulse the flour with the sugar and salt. Add the butter and pulse until the mixture resembles coarse meal. Transfer to a bowl and stir in the ice water. Knead the dough 2 or 3 times on a lightly floured surface and pat into a disk. Wrap in plastic and refrigerate for at least 30 minutes.
On a lightly floured surface, roll out the dough to a 12-inch round. Fit the dough into a 9-inch glass pie plate. Trim the overhang to 1/2 inch, fold the edge under itself and crimp decoratively. Refrigerate until firm.
Making the filling
Preheat the oven to 375°. On a baking sheet, toast the pecans for about 8 minutes, or until fragrant; chop coarsely.
In a large bowl, whisk the eggs with the brown sugar, corn syrup, vanilla, melted butter, bourbon and salt until blended. Stir in the pecans and chocolate chips until evenly distributed.
Pour the filling into the pie shell. Bake on the bottom shelf of the oven for about 55 minutes, or until the center of the pie is set. Tent the crust with foil halfway through the baking time if the edge is browning too quickly. Transfer the pie to a rack and let cool for at least 1 hour before serving.
Note: The pie can be stored at room temperature for up to 1 day. Rewarm if desired at 325° for 15 minutes.
