<human>:  How do I cook a flaky and tender pie crust?
<bot>: 
1. Start by preheating the oven to 425°F (218°C).
2. Mix together 2 cups (250g) of all-purpose flour, 1 teaspoon (5g) of salt, and 1/3 cup (68g) of cold butter or vegetable shortening in a large bowl or in the bowl of a stand mixer.
3. Work the butter or shortening into the flour with your hands, a pastry blender, or paddle attachment of the stand mixer until it is in pea-sized pieces.
4. Add 4-6 tablespoons (60-90ml) of cold water to the mixture, a tablespoon at a time.
5. Roll the dough on a lightly floured surface until it forms a large, thin circle around 12 inches (30cm).
6. Prick the bottom of the dough with a fork.
7. Bake the crust for 15 minutes.
