1 1/2 cups all-purpose flour
1/2 cup confectioner’s sugar
1/4 teaspoon salt
1 stick plus 1 tablespoon (9 tablespoons; 4 1/2 ounces) very cold (or frozen) unsalted butter, cut into small pieces
1 large egg yolk
Put the flour, sugar and salt in the bowl of a food processor and pulse a few times to combine. Scatter the pieces of butter over the dry ingredients and pulse until the butter is coarsely cut in—you should have pieces the size of oatmeal flakes and some the size of peas. Stir the yolk, just to break it up, and add it a little at a time, pulsing after each addition. When the egg is in, process in long pulses—about 10 seconds each—until the dough, which will look granular soon after the egg is added, forms clumps and curds. Just before you reach this stage, the sound of the machine working the dough will change—heads up. Turn the dough out onto a work surface and, very lightly and sparingly, knead the dough just to incorporate any dry ingredients that might have escaped mixing. Chill the dough, wrapped in plastic wrap, for about 2 hours before rolling.*
To roll the dough: Butter a 9-inch fluted tart pan with a removable bottom. Roll out chilled dough on floured sheet of parchment paper to 12-inch round, lifting and turning dough occasionally to free from paper. Using paper as aid, turn dough into 9-inch-diameter tart pan with removable bottom; peel off paper. Seal any cracks in dough. Trim overhang to 1/2 inch. Fold overhang in, making double-thick sides. Pierce crust all over with fork.
Freeze the crust for at least 30 minutes, preferably longer, before baking.
To fully bake the crust: Center a rack in the oven and preheat the oven to 375°F. Butter the shiny side of a piece of aluminum foil (or use nonstick foil) and fit the foil, buttered side down, tightly against the crust. (Since you froze the crust, you can bake it without weights.) Put the tart pan on a baking sheet and bake the crust for 25 minutes.
Carefully remove the foil. If the crust has puffed, press it down gently with the back of a spoon (or prick it with the tip of a small knife). Bake the crust about 10 minutes longer, or until it is firm and golden brown, brown being the important word: a pale crust doesn’t have a lot of flavor. Transfer the pan to a rack and cool the crust to room temperature.
Storing: The dough can be wrapped and kept in the refrigerator for up to 5 days or frozen for up to 2 months. While the fully baked crust can be packed airtight and frozen for up to 2 months, the flavor will be fresher bake it directly from the freezer, already rolled out–just add about 5 minutes to the baking time.
* Alternate press-in technique: If you want to use the press-in method, you can work with the dough as soon as it’s processed. Just press the dough evenly over the bottom and up the sides of the pan. Don’t be too heavy-handed–press the crust in so that the edges of the pieces cling to one another, but don’t press so hard that the crust loses its crumbly texture.
