<human>:  How do I make a pie crust?
<bot>: To make a pie crust, start by combining 1 and 1/2 cups of all-purpose flour, 1/2 teaspoon of salt, and 1/2 cup of cold butter cut into cubes. Mix the butter into the flour until it resembles coarse crumbs. Slowly add 4-6 tablespoons of ice cold water, just until the dough comes together. Gently knead a few times, then form into a ball and flatten into a disk. Wrap in plastic wrap and place in the refrigerator for at least an hour, or up to three days. When ready to use, roll out dough into a circle and place in a 9-inch pie dish. Trim the edges and flute them with your fingers or a fork and fill with desired filling. Bake as instructed for your recipe.
