Step 1: Make the Pastry
Combine Dry Ingredients: In a large mixing bowl, mix the flour, sugar, and salt together.
Add Butter: Add the softened butter and mix until the mixture resembles coarse crumbs.
Incorporate Egg and Vanilla: Add the egg and vanilla extract. Mix until the dough comes together. If it’s too dry, add a bit of cold water.
Chill the Dough: Form the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
Step 2: Prepare the Custard Filling
Heat Milk: In a saucepan, heat the milk over medium heat until it’s just about to simmer.
Mix Sugar and Cornstarch: In a separate bowl, whisk together sugar, cornstarch, and eggs until smooth.
Combine Mixtures: Gradually add the hot milk to the egg mixture while whisking constantly to prevent curdling. Return this mixture to the saucepan and cook over low heat until thickened, about 5-10 minutes. Stir in the vanilla extract and lemon zest.
Cool Custard: Once thickened, transfer the custard to a bowl and cover with plastic wrap, pressing it directly onto the surface to prevent a skin from forming. Let it cool.
Step 3: Assemble the Torta
Preheat Oven: Preheat the oven to 350°F (175°C).
Roll Out the Dough: On a floured surface, roll out the pastry dough to fit your tart pan (about 1/8 inch thick).
Line the Tart Pan: Place the rolled dough in the tart pan, trimming off any excess. Prick the bottom with a fork to prevent bubbling.
Fill with Custard: Pour the cooled custard filling into the pastry shell and spread evenly.
Add Toppings: Sprinkle pine nuts on top for added flavor and crunch.
Step 4: Bake the Tart
Bake: Place the tart in the oven and bake for 35-40 minutes, or until the pastry is golden brown and the custard is set.
Cool: Once baked, let the tart cool completely in the pan before removing.
Step 5: Serve
Garnish: Dust with powdered sugar and lemon zest before serving.
Slice and Enjoy: Cut into wedges and enjoy this delightful Italian treat!
Variations
Chocolate Variation: Add melted chocolate to the custard for a rich chocolate flavor.
Fruit Filling: Substitute half of the custard with fresh fruit like strawberries or peaches.
Nut-Free Option: Omit the pine nuts or substitute with slivered almonds or pecans.
