Preparation

• Put the flour, sugar, and salt in a food processor; pulse briefly to combine. Add the butter and shortening; pulse just until coarse crumbs form, about 30 seconds. Add the lemon juice and water. Pulse just until moist crumbs form. Turn the dough onto a work surface and gently shape it into two equal disks about 4 or 5 inches in diameter. Wrap in plastic and refrigerate at least 1 hour or up to 1 day.
• 对于单壳派— Roll one disk of dough between two large pieces of lightly floured parchment. Roll into a 14-inch-diameter round that’s 1/8 inch thick. Remove the top sheet of parchment. Gently roll the dough around the pin and position the pin over the pie pan. Unroll, gently easing the dough into the pan, gently but firmly pressing the dough against the sides and bottom, taking care not to pull or stretch. With scissors, trim the edge of the dough, leaving a 3/4-inch margin from the outer edge of the pan. Tuck this dough under to shape a high edge crust that rests on top of the rim. Pinch-crimp the crust.
• For blind baking— Follow the steps for a one-crust pie (above). Freeze the crust for at least 30 minutes. Heat the oven to 425°F. Line the frozen crust with a large piece of foil, fill with pie weights (or dried beans or rice), and bake 12 minutes. Remove the foil and weights and continue baking the shell until golden, about 8 minutes longer, checking for bubbles (push them down gently with the back of a spoon).
• For a double crust- 将一个面团铺开，因为一个壳派，并在9英寸的派锅上排成一盘，将多余的悬挂在侧面。当您在羊皮纸之间推出另一个磁盘时，用塑料松散地盖住。将馅料加载到外壳中。用水刷底部的边缘。将顶层滚动在销钉上，并将其放在馅饼上。轻轻展开，将面团居中在馅料上。将边缘压在一起，并用剪刀将两层剪切，使它们比馅饼锅的外边缘大1/2英寸。将这个面团塞在下面，形成一个高边缘，该面包皮放在轮辋顶部。照片中的捏碎。用一把削皮刀，在顶部地壳上砍下两个或三个通风孔，并按照食谱指示烘烤。
• 对于格子地壳- 将一个面团铺开，因为一个壳派，并在9英寸的派锅上排成一盘，将多余的悬挂在侧面上。将羊皮纸之间的另一个磁盘铺成略大于14×9英寸的矩形时，用塑料松散地盖住塑料。取下羊皮纸的顶层。将面团修剪成精确的14×9英寸矩形。切12条长14英寸，宽3/4英寸。如果面团变软，请滑动羊皮纸，然后将面团在烤盘上短暂冷却，然后再继续。在衬有羊皮纸的烤盘上，水平排列6条条，将它们相距3/4英寸；这些将是“底部”条。将其余的放在单独的羊皮纸上；这些将是“顶部”条。
• 做格子（请参阅照片）：如果您在工作时面团变暖，请在冰箱中短暂冷却。

  1. Fold back every other bottom strip, starting closest to you. Slightly right of center, lay one top strip vertically.
