To prepare the crust, combine flour and salt in a food processor and pulse.
Add the chilled butter, pulsing until pea-sized lumps form.
Gradually add ice water, one tablespoon at a time, until the dough holds together.
Gather the dough into a ball, flatten it into a disk, wrap in plastic, and refrigerate for at least 1 hour (or up to 2 days).
Once chilled, roll the dough out on a floured surface to a 12-inch circle.
Place it in a 9-inch pie plate, crimping the edges after trimming the excess.
Prick the base with a fork and chill for another 30 minutes.
Preheat your oven to 375°F.
Line the crust with foil and fill with pie weights or beans. Bake for 25 minutes, then remove the foil and bake for an additional 5 to 10 minutes until lightly golden.
Lower the oven temperature to 350°F. Toast the pecans on a baking sheet for about 8 to 10 minutes, shaking the pan occasionally. Let them cool.
For the filling, melt the butter and chopped chocolate gently in a small saucepan over low heat until smooth; allow to cool.
In a large bowl, combine the cooled chocolate-butter mixture with corn syrup, eggs, sugar, cocoa powder, bourbon, and salt.
Pour this filling into the prepped crust, topping it with the toasted pecans.
Bake the pie on a baking sheet until the filling is set but still jiggles slightly, about 30 to 40 minutes.
Allow the pie to cool thoroughly on a wire rack before slicing. Enjoy a slice with vanilla ice cream for a special treat!
