Move the oven rack to the middle position then preheat to 350 degrees F. Spread the 8 ounces pecans on a baking sheet then roast in the oven for around 10 minutes or until they are fragrant.
Fry the 6 strips bacon over medium low heat until brown and very crisp then transfer to a paper towel lined plate to cool. Measure 2 Tbs of bacon lard into a glass or metal container then allow it to come to room temperature before placing it in the freezer. Put 9 pieces of the fried bacon (3 whole strips) in the freezer as well.
Put the frozen bacon into the work bowl of a food processor and blitz until the bacon is powderized.
Add the 1 ¼ cups flour and 2 tablespoons evaporated cane sugar, processing until it's well incorporated into the flour.
Add the frozen 2 tablespoons bacon grease and 8 tablespoons cultured unsalted butter, then pulse until there are pebble sized pieces of fat.
Whisk together 1 egg with 1 tablespoon ice water of ice water. Add 2 tablespoons of this mixture too the food processor and then pulse to combine. Continue to add more of the egg mixture and pulse until the dough is crumbly but just starting to come together (pictured above). You shouldn't need to use all of the egg mixture.
Turn the pebbles of dough out onto a sheet of plastic wrap and press together. Using as few motions as possible, flatten the dough with the palm of your hand then use the plastic wrap to fold the dough over itself. The idea is to flatten the beads of cold butter into layers, which will make the dough flaky. Too much handling though and you will form gluten in the flour which will make the dough tough. Flatten once more, fold over and shape into a puck. Wrap with the plastic and put it in the refrigerator for at least 1 hour.
On a floured surface, roll out the dough so it's bigger than a standard pie plate.
Roll it onto your pin and slide it over your pie plate. Unroll it making sure it's centered. Gently press the dough into the corners of the plate and then use kitchen sheers to trim the dough with ½" of overhang. Tuck the overhang under itself then flute the edge with your fingers. Return to the fridge until hard.
Preheat the oven to 400 degrees F and cover the crust with aluminum foil, pressing the foil against the dough. Use a fork to poke holes through the foil and through the dough. Dump some dried beans or pie weights onto the foil and put the crust into a preheated oven. Bake for 15 minutes or until the crust is set.
Remove the foil with the pie weights and return the crust to the oven until it just starts turning brown 7-10 minutes.
Turn the oven down to 275 degrees.
Setup a double boiler with a metal bowl over a pot filled with water and bring the water to a gentle simmer. Melt the 6 tablespoons cultured unsalted butter, then add the 1 cup dark brown sugar, ¾ cup light corn syrup, and ¼ teaspoon salt.
Once they're dissolved, whisk in the 3 large eggs one at a time until combined. Switch to a heatproof spatula and mix in the 1 teaspoon vanilla extract and 1 tablespoon bourbon. Continue stirring, scraping the bottom and sides of the bowl until the mixture reaches 130 degrees F.
Remove it from the heat, add the pecans and pour the mixture into the warm crust.
Bake for 50-60 minutes or until the center is mostly set. Insert the remaining 9 pieces of bacon into the top of the pie while it is still warm. Let it cool completely before cutting.
