Tart Crust Recipes

Steps:

• Dice the butter and return it to the refrigerator while you prepare the flour mixture. Place the flour, salt, and sugar in the bowl of a food processor fitted with a steel blade and pulse a few times to mix. Add the butter and shortening. Pulse 8 to 12 times, until the butter is the size of peas. With the machine running, pour the ice water down the feed tube and pulse the machine until the dough begins to form a ball. Dump out on a floured board and roll into a ball. Wrap in plastic wrap and refrigerate for 30 minutes.
• Cut the dough in half. Roll each piece on a well-floured board into a circle, rolling from the center to the edge, turning and flouring the dough to make sure it doesn't stick to the board. Fold the dough in half, place in a pie pan, and unfold to fit the pan. Repeat with the top crust.

Steps:

• Put the flour, sugar and salt into the bowl of a food processor, and pulse once or twice to mix. Add the butter, and pulse twice more, so it's still in very large pieces. Steadily pour the ice water into the machine while pulsing it as quickly as you can, until the butter is still visible in large smears and the dough is pushing up the sides of the bowl and looks like damp bread crumbs (you may not need to add all the water).
• Scrape the dough crumbs into a bowl, cover and refrigerate for at least 1 hour. (The dough will continue to hydrate, but if it still feels powdery and dry, wet your fingertips and flick a little cold water onto the crumbs.) After 1 hour, divide the dough into two even balls, gently squashing each into a disc, and wrap each in plastic wrap. Put one in the fridge, to roll out for the potato-and-radicchio tart, and put the other in the freezer so that you have dough ready to go for another tart.

Steps:

• Blend flour and salt in processor. Add butter; using on/off turns, cut in until mixture resembles coarse meal. Add 3 tablespoons ice water and cream. Process just until moist clumps form, adding more ice water by teaspoonfuls if dough is dry. Gather dough into ball; flatten into disk. Wrap in plastic; chill 1 hour. (Can be made 2 days ahead. Keep chilled. Soften slightly at room temperature before rolling out.)
