- 2 1/2 cups all purpose flour
- 1 tablespoon sugar
- 2 teaspoons ground ginger
- 2 teaspoons ground cinnamon
- 1/2 teaspoon salt
- 10 tablespoons (1 1/4 sticks) chilled unsalted butter, cut into 1/2-inch cubes
- 1/2 cup chilled solid vegetable shortening, cut into pieces
- 4 tablespoons (or more) ice water
- 2/3 cup (packed) golden brown sugar
- 1/4 cup cornstarch
- 1 teaspoon fresh lemon juice
- 1/2 teaspoon ground ginger
- 1/2 teaspoon ground cinnamon
- 3 pounds medium peaches
- Whisk first 5 ingredients in medium bowl to blend. Add butter and shortening and rub in with fingertips until mixture resembles very coarse meal. Mix in 4 tablespoons ice water. Mix in more water by tablespoonfuls if dough is dry, tossing until moist clumps form. Gather dough into ball. Divide dough into 2 pieces, 1 slightly larger than the other. Flatten into disks; wrap and chill at least 2 hours and up to 2 days.
- Mix sugar, cornstarch, lemon juice and spices in large bowl. Bring medium saucepan of water to boil. Drop in 3 peaches at a time; blanch 1 minute. Transfer peaches to bowl of cold water. Using small sharp knife, peel 1 peach. Cut peach in half; discard pit and slice thinly. Stir peach slices into sugar mixture. Repeat with remaining peaches. Let filling stand until juices form, at least 30 minutes and up to 1 hour.
- Preheat oven to 375°F. Roll out larger dough disk on lightly floured surface to 13- to 14-inch round. Transfer to 9-inch-diameter deep-dish pie dish. Roll out smaller dough disk on lightly floured surface to 11-inch round. Using ruler as aid, cut dough into 1/2-inch-wide strips.
- Spoon filling into dough-lined dish. Arrange some of dough strips atop pie, spacing 3/4 inch apart. Form lattice by arranging more dough strips at right angle to first strips, spacing 3/4 inch apart. Trim overhang of bottom crust and lattice strips to 3/4 inch. Fold under and crimp edge decoratively.
- Bake pie until crust is golden and filling bubbles thickly, covering edge of crust with foil if browning too quickly, about 1 hour 20 minutes. Cool pie to room temperature before serving.
