Hi,
You need fat (butter, lard or shortening) to make the pie crust in addition to the flour and water. Make sure everything is very cold to get the best results. Try this recipe. It may sound a little complicated if you're not used to baking, but it's not terribly difficult. I like this recipe because it has lots of good hints of what things should look like as you work.
Flaky Pastry Dough (from Joy of Cooking)
Makes 2 nine-inch pie crusts (bottom only), or 2 9-1/2 or 10-inch tart crusts, or one 9-inch covered pie crust
Mix together:
2-1/2 c. all-purpose flour
1 teaspoon white sugar (or 1 T powdered sugar)
1 teaspoon salt
Add:
1 cup solid vegetable shortening, or 1/2 cup shortening and 8 tablespoons (1 stick) cold unsalted butter
Break the shortening into large chunks; if using butter, cut it into small peices, then add it to the flour mixture. Cut the fat into the dry ingredients by chopping vigorously with a pastry blender or by cutting in opposite directions with 2 knives, one held in each hand (**You can use a fork, too. You're breaking up the fat into tiny little coated with flour.) As you work, periodically stir dry flour up from the bottom of the bowl and scrape clinging fat off the pastry blender or knives. When you are through, some of the fat wshould remain in pea-sized pieces; the rest should be reduced to the consistency of coarse crumbs or cornmeal. The mixture should seem dry and powdery and not pasty or greasy.
Drizzle over the flour and fat mixture:
1/3 cup plus 1 tablespoon ice water
Using a rubber spatula, cut with the blade side until the mixture looks evenly moistened and begins to form small balls. Press down on the dough with the flat side of the spatula. If the balls of dough stick together, you have added enough water; if they do not, drizzle over the top 1-2 tablespoons ice water. Cut in the water, again using the blade of the spatula, then press with your hands until the dough sticks together. The dough should look rough, not smooth. Divide the dough in half, press each half into a round flat disk, and wrap tightly in plastic. Refrigerate for at least 30 minutes, and preferably for several hours, or for up to 2 days before rolling. The dough can also be wrapped airtight and frozen for up to 6 month; thaw completely before rolling.
You can also pulse the fat and dry ingredients together in a food processor, add the water and pulse again to create the crumbles.
Roll out press into pie pan. Refrigerate for at least 30 minutes. Position a rack in teh lower third of the oven. Preheat the oven to 400. Cover with foil, touching the sides and bottom of the crust. Fill with dry beans or rice to weight it. Bake for 20 minutes. Lift out foil and weights (will be HOT). Prick the crust with a fork and continue baking 5-10 minutes more. Press down GENTLY with the back of a spoon.
If you are filling the crust with an uncooked mixture that requires further baking, whisk together, then brush the inside with 1 large egg yolk and a pinch of salt. Return to the oven until the egg glaze sets, 1-2 minutes. Fill the shell at once while still hot, or let cool as specified in the recipe.
