Place the alcohol in a measuring cup and add the cold water. Place it in the freezer while you prepare the other ingredients.
1 Tbsp whiskey , 1/4 cup cold water
Place the flour and salt in the bowl of the food processor. Place the whole bowl in the freezer while you cube the butter.
1 1/4 cup (150g) all-purpose flour , 1/4 tsp fine sea salt
Add the cubed butter to the flour in the freezer, for 5-10 minutes.
1/2 cup (113g) salted butter
Remove the the bowl from the freezer, place it on the food processor and pulse until pea seize chunks form.
While the food processor is on, stream in the water mixture just until it starts to come together. Start with only 2 Tbsp of water and use up to 1/4 cup if needed, I usually do 1/4 cup + 1 Tbsp of alcohol. You want the dough to be kinda crumbly but stick together when you press on it.
Remove the dough from the food processor, press it together so it all sticks together. Wrap it in plastic wrap and refrigerate it for an hour (or overnight).
Preheat the oven to 425F (218C) conventional (no fan).
Place a sheet of parchment paper on the chilled pie dough and fill it in with pie weights (or rice) to keep the sheet in place.
Bake the pie crust on the bottom rack of the oven for 20 minutes, until it starts to get some color.
Remove from the oven and remove the pie weights and parchment sheets. Allow the crust to cool completely (if it's hot when you pour the filling, you may have a soggy bottom).
