- Filling:
 - 1 1/2 pounds ricotta cheese
 - 6 eggs, separated
 - 1/2 cup white sugar
 - 1/4 teaspoon lemon juice
 - 1/4 teaspoon lemon zest
 - 1/2 teaspoon vanilla extract
 - Crust:
 - 2 cups all-purpose flour
 - 6 tablespoons white sugar
 - 1 teaspoon baking powder
 - 1/8 teaspoon salt
 - 1/2 cup butter
 - 1/4 cup milk
 - 1 egg
 - 2 tablespoons lemon zest
 
- To Make the Crust: Combine the flour, 6 tablespoons white sugar, baking powder, salt, and lemon zest. Cut in the butter until the mixture resembles coarse crumbs. Stir in the milk and the 1 egg. Work dough until it forms a ball. Do not knead or over work the dough. Generously flour a work surface and roll dough out to fit into a 9-inch pie plate. Place dough in a greased pie plate. Poke holes in the center with the tines of a fork. Do not prebake.
 - Preheat oven to 350 degrees F (175 degrees C).
 - Beat ricotta, yolks, and sugar until lemon colored. Add lemon juice, zest, and vanilla.
 - Beat whites until stiff, fold into lemon mixture. Pour mixture into the prepared shell. Do not over fill the shell, it rises slightly when baking.
 - Bake at 350 degrees F (175 degrees C) for 45 to 50 minutes. Let pie cool then refrigerate to set; the pie will become creamy and dense. Serve cold.
