PreparationFor crust: Blend flour, sugar and salt in processor. Add butter and shortening and cut in using on/off turns until mixture resembles coarse meal. Add 6 tablespoons ice water and process until moist clumps form, adding more water by teaspoonfuls if dough is dry. Gather into ball; divide into 2 pieces. Flatten each into disk. Wrap each in plastic; chill 2 hours. (Can be made 2 days ahead. Keep chilled. Let dough soften slightly before rolling out.) For filling: Position rack in lowest third of oven and preheat to 400°F. Mix first 6 ingredients in large bowl. Add apples and toss to blend. Roll out 1 dough disk on floured surface to 12-inch round. Transfer to 9-inch-diameter glass pie dish. Fold edge under, forming high-standing rim; crimp. Add filling. Roll out second dough disk on floured surface to 13-inch round. Cut into twelve 1-inch-wide strips. Arrange 6 strips across pie. Form lattice by arranging 6 strips diagonally across first strips. Gently press ends into crust edges. Brush lattice with milk. Sprinkle lightly with additional sugar. Bake pie 10 minutes. Reduce oven temperature to 375°F. Continue baking until juices bubble thickly and crust is deep golden, covering edges with foil if browning too quickly, about 1 hour 20 minutes. Cool on rack 1 hour. (Can be made 8 hours ahead. Let stand on rack.)
