1 vanilla bean, split lengthwise, seeds scraped and reserved
3 tablespoons (24 grams) cornstarch
1teaspoon (3 grams) kosher salt
1 large egg, lightly beaten
2 tablespoons (24 grams) turbinado sugar
Instructions
On a lightly floured surface, roll half of dough into a 12-inch circle. Transfer to a 9-inch pie plate, pressing into bottom and up sides. Trim dough to ½ inch beyond edge of plate. Fold edges under, and crimp as desired. Freeze for 30 minutes.
Preheat oven to 375°F.
In a medium saucepan, combine blueberries, granulated sugar, lemon zest and juice, vanilla bean seeds, cornstarch, and salt over medium heat. Stir gently, being careful not to crush berries. Bring to a simmer, and cook until thickened, 5 to 10 minutes. Remove from heat, and let cool. Pour filling into prepared crust.
On a lightly floured surface, roll remaining dough to ¼-inch thickness. Using a sharp knife or pizza wheel, cut dough into ½-inch strips. Braid dough strips, and arrange on top of filling, tucking ends under. Reroll scraps, and cut remaining dough into long ¼-inch strips. Braid dough strips, and arrange around edge of crust. Brush dough with beaten egg, and sprinkle with turbinado sugar. Place pie on a baking sheet.
Bake until golden brown and bubbly, 40 to 50 minutes, covering with foil halfway through baking to prevent excess browning, if necessary.
