Neapolitan Easter Pie

1. Vanilla Pastry Cream:

   Bring milk and vanilla seeds and pod to a simmer in a medium saucepan. Remove from heat. Cover; let stand 20 minutes.

2. In a large bowl, whisk egg yolks until smooth. In a medium saucepan, combine sugar and cornstarch. Gradually add milk mixture in a slow, steady stream and cook over medium heat, stirring constantly, until mixture thickens and begins to bubble, about 5 minutes.

3. Whisking constantly, slowly pour one-third of milk mixture into egg yolks. Pour mixture into remaining milk in saucepan. Cook over medium heat, whisking constantly, until mixture comes to a full boil and is thick enough to coat the back of a spoon, 2 to 4 minutes. Remove from heat.

4. Strain mixture through a fine sieve into a heatproof bowl; discard solids. Cover with parchment or plastic wrap, pressing directly on surface to prevent a skin from forming. Refrigerate until well chilled and firm, at least 2 hours or up to 2 days. Whisk to soften slightly just before using.

5. Crust:

   In a medium bowl, whisk together flour, baking powder, and salt. With an electric mixer on medium speed, beat butter and sugar until pale and fluffy, about 3 minutes. Beat in orange zest. Add eggs, one at a time, beating until each is fully incorporated. Reduce speed to low, and beat in flour mixture.

6. Divide dough into 2 disks, one larger (approximately two-thirds of dough) and one smaller. Press each piece into a disk; wrap in plastic and refrigerate 1 hour or up to 1 day.

7. Filling:

   Place wheat berries in a medium bowl. Add enough water to cover by 2 inches. Refrigerate overnight.

8. Drain wheat berries, and transfer to a medium saucepan with milk, water, butter, and salt. Bring to a boil, then reduce to a simmer, and cook until tender, about 1 hour. Drain, and spread on a baking sheet. Let cool about 30 minutes.

9. Preheat oven to 375 degrees. In a medium bowl, stir together ricotta and sugar. Add cooled wheat berries and pastry cream. Stir to combine.

10. On a lightly floured surface, roll out larger piece of dough to a 14-inch round, about 1/8 inch thick. Fit into a 10-by-2-inch springform pan. Pour filling into shell. Trim excess dough to 1/2 inch above filling. Roll out remaining piece of dough, 1/8 inch thick. With a pastry wheel, cut into twelve 3/4-inch strips. Weave strips into a lattice over filling; trim lattice flush with edge of dough.

11. Lightly beat egg and brush evenly over top of pie. Bake until crust is golden and filling is bubbling, 60 to 90 minutes. Transfer to a wire rack, and let cool 20 minutes. Run a sharp knife around edge to gently loosen pie. Remove outer ring from springform pan. Let pie cool completely. Serve.
