NEAPOLITAN EASTER PIE

Steps:

• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• Filling:Place wheat berries in a medium bowl. Add enough water to cover by 2 inches. Refrigerate overnight.
• 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.
• Preheat oven to 375 degrees. In a medium bowl, stir together ricotta and sugar. Add cooled wheat berries and pastry cream. Stir to combine.
• 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.
• 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.
