1 vanilla bean, split lengthwise, seeds scraped and reserved
Buttermilk Pie Dough (recipe follows)
1 large egg
1 tablespoon water
Instructions
In a large bowl, combine peaches, blackberries and orange juice.
In a small bowl, stir sugar, cornstarch, salt, orange zest, and vanilla bean seeds. Sprinkle mixture over fruit; toss gently.
Preheat oven to 375º.
On a lightly floured surface, roll 1 disk Buttermilk Pie Dough into a 12-inch circle. Transfer to a 9-inch deep-dish pie plate, pressing into bottom and up sides. Trim dough to ½ inch beyond edge of plate. Spoon fruit filling into dough.
On a lightly floured surface, roll remaining disk into a 12-inch circle. Cut dough into 1-inch-wide strips. Place dough strips on pie in a lattice design. Trim dough strips, fold edges under, and crimp as desired. For leaf decoration, gather dough scraps and roll into a ⅛-inch thickness. Using leaf-shaped cutter, cut leaves. Decorate top crust with leaves. To create flowers, cut ¾-inch circles. Roll one up to create the bud center. Thin out edge on three circles, and wrap petals around center bud. Repeat process with 5 more petals. Pinch bottom to seal and place on pie. Place pie on a baking sheet.
In a small bowl, whisk together egg and 1 tablespoon water. Using a pastry brush, lightly coat top crust with egg wash.
Bake until interior is bubbling and crust is golden brown, 1 hour 45 minutes to 2 hours, covering crust with foil halfway through to prevent over-browning. Let cool for 2 hours before slicing.
Note: To prevent a soggy crust, preheat baking sheet in a 400º oven for 15 minutes before placing pie directly on pan.
