For a 9 inch Double Crust
3 cups all purpose flour
¼ cup sugar
1 ½ tsp salt
2 ½ sticks very cold unsalted butter, cut into tbsp size pieces
1/3 cup very cold vegetable shortening, cut into 4 pieces (or use margarine for both the butter and shortening)
About ½ cup ice water
Put the flour, sugar, and salt in a food processor fitted with a metal blade, pulse just to combine the ingredients. Drop in the butter and shortening and pulse only until the butter and shortening are cut into the flour. Don’t overdo the mixing- what you’re aiming for is to have some pieces the size of fat green peas and others the size of barley. Pulsing the machine on and off, gradually add about 6 tbsps of the water- add a little water and pulse once, add some more water, pulse again and keep going that way. Then use a few long pulses to get the water into the flour. If, after a dozen or so pulses, the dough doesn’t look evenly moistened or form soft curds, pulse in as much of the remaining water as necessary, or even a few drops more, to get a dough that will stick together when pinched. Big pieces of butter are fine. Scrape the dough out of the bowl and onto a work surface.
Divide the dough in half. Gather each half into a ball, flatten each ball into a disk and wrap each half in plastic. Refrigerate the dough for at least 1 hour before rolling (if your ingredients were very cold and you worked quickly, though, you might be able to roll the dough immediately: the dough should be as cold as if it had just come out of the fridge).
To Roll Out the Dough: Have a buttered 9 inch pie plate at hand.
You can roll the dough out onto a floured surface or between sheets of wax paper or plastic wrap or in a rolling slipcover. If you’re working on a counter, turn the dough over frequently and keep the counter floured. If you are rolling between paper, plastic or in a slipcover, make sure to turn the dough over often and to life the paper, plastic, or cover frequently so that it doesn’t roll into the dough and form creases.
If you’ve got time, slide the rolled out dough into the fridge for about 20 minutes to rest and firm up.
Butter a 9-inch deep-dish pie plate (I use a Pyrex pie plate). If you want to use a standard 9-inch pie plate, just reduce the amount of filling by about one quarter.
Working on a well-floured surface (or between wax paper or plastic wrap), roll out one piece of the dough to a thickness of about 1/8 inch.
Fit the dough into the buttered pie plate and trim the edges to a 1/2-inch overhang. Roll the other piece of dough into a 1/8-inch-thick circle and slip it onto a baking sheet lined with parchment or a silicone mat. Cover both the circle and the crust in the pie plate with plastic wrap and refrigerate for about 20 minutes, while you preheat the oven and prepare the filling.
Add your filling, lay the top crust and crimp as you like. Make sure to cut steam slits in the top crust. Brush with a little milk or cream and sprinkle some sugar on top.
Bake at 425 degrees F for about 15 minutes, and then lower the oven to 375 degrees F and bake the pie for another 50-60 minutes. If there is a fruit filling, it should be bubbling.
After about 40 minutes in the oven, if the top crust looks as if it’s browning too quickly, cover the pie loosely with a foil tent.
Transfer the pie to a rack and let it rest until it is only just warm or until it reaches room temperature.
