FOR THE FILLING:
In a heavy-bottomed medium saucepan, mix together sugar, flour, and salt.
In a separate mixing bowl, beat together the egg yolks and milk.Whisk the egg mixture into the dry ingredients in the saucepan. Continue whisking over low heat until the mixture coats the back of a spoon and is smooth and thick.
Remove from the heat and stir in the butter and vanilla.
Cook's Note: Add any variations at this point (variations listed under directions).
Allow the mixture to cool and pour into the baked pie shell. Chill the pie completely and top with fresh whipped cream or other desired topping.
FOR THE PIE DOUGH:
Preheat the oven to 425 degrees F.
In a mixing bowl, mix together the flour and the salt; cut or work the butter into the flour with your fingers or a pastry blender until you have large pea sized chunks scattered throughout. Alternatively,pulse the dough in a food processor, or mix in a stand mixer with the paddle attachment on low speed.
Add the ice water slowly while stirring with a fork, or in the food processor or mixer, until just combined. Be careful not to overwork the dough. Divide the dough into two disks, flatten and refrigerate each for at least 15 minutes.
Roll out one chilled pie dough to fit a 9-inch pie plate. Reserve the second pie dough disc for another use. Transfer dough to pie plate, pressing the dough lightly into the plate; trim the edges. Dock the dough with the prongs of a fork evenly over the bottom of the pie plate. Line the docked dough with aluminum foil and fill with pie weights or dried beans.
Bake the pie crust until the edges are brown and golden, about 15 minutes Remove from the oven and remove the weights. Return crust to the oven to finish baking for another 5 minutes.
