<human>:  How do I make the perfect pie crust?
<bot>: The perfect pie crust requires the right combination of ingredients and a careful technique. Start by combining 1 ½ cups (190g) of all-purpose flour, ½ teaspoon (2.5g) of table salt, and 6 tablespoons (90g) of cold, unsalted butter cut into small pieces. Using a pastry blender or your fingertips, mix the butter into the flour until the mixture resembles coarse meal with some larger pieces of butter remaining. Add 4 tablespoons (60ml) of cold water and mix until the dough comes together. Gently knead the dough until it holds together, then form it into a disc and wrap in plastic wrap. Refrigerate for at least 1 hour before rolling out the dough. When ready to use, roll the dough out on a lightly floured surface and fit it into your pie dish. Prick the bottom and sides of the crust with a fork and pre-bake before adding your filling.
