<human>:  How do you make a pie crust?
<bot>: To make a pie crust, you will need all-purpose flour, salt, unsalted butter, and cold water. First, combine the flour and salt in a bowl. Cut the butter into the flour mixture with a pastry cutter, two knives, or your hands until the butter is in tiny pieces and evenly distributed. Slowly add cold water, stirring with a fork, until the dough comes together. Wrap the dough in plastic wrap and refrigerate for at least an hour before using. When ready, roll the dough on a lightly floured surface to the desired size, and fit it into your pie pan.
