vegetable shortening: cubed and chilled unsalted butter: cubed and chilled peaches: peeled and cut into 0.6cm thick slices
Make the crust: Whisk together flour, sugar, and salt in a large bowl; add shortening and butter, and rub them into the flour until pea-size crumbles form. Make a well in center of flour mixture; add vinegar, egg, and 6 tbsp. ice-cold water. Using a fork, stir until dough forms. Transfer to a lightly floured surface and knead to combine; form dough into a ball; halve, and form each half into a disk. Wrap disks in plastic wrap; refrigerate for 1 hour.
Make the filling: In a large bowl, toss together sugar, flour, brown sugar, juice, schnapps, vanilla, cinnamon, ginger, salt, nutmeg, and peaches; set aside. Heat oven to 220°C. Roll one dough disk into a 30cm circle; fit into a 23cm pie plate. Pour half the filling into pie shell and cover with raspberries. Pour in remaining peach filling, and then dot filling with butter. Roll the remaining dough disk into a 30cm circle, place over filling, and trim dough, leaving a 0.6cm overhang. Lift edges and fold under to form a thick rim around the pie. Cut 4 slits in top of pie crust, and sprinkle with more sugar. Bake until golden brown and filling is bubbling in the center, about 45 minutes. Let cool for about 20 minutes before serving.
