Step 1: Make the Pastry Crust
Mix Ingredients: In a mixing bowl, combine the flour, sugar, and salt. Add the softened butter and mix until crumbly.
Add Egg and Vanilla: Stir in the egg and vanilla extract until the dough comes together.
Chill the Dough: Shape the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
Step 2: Prepare the Pastry Cream
Heat Milk: In a saucepan, heat the milk and half of the sugar over medium heat until it starts to steam. Do not let it boil.
Whisk Egg Yolks and Sugar: In a separate bowl, whisk the egg yolks, cornstarch, and remaining sugar until smooth.
Combine: Gradually pour the hot milk into the egg mixture while whisking constantly to prevent curdling.
Thicken the Mixture: Return the mixture to the saucepan over medium heat, whisking until it thickens (about 2-3 minutes). Remove from heat and stir in the butter and vanilla. Let it cool completely.
Step 3: Assemble the Crostata
Preheat Oven: Preheat the oven to 350°F (175°C).
Roll Out the Dough: On a floured surface, roll out the chilled dough to fit your tart pan.
Bake the Crust: Place the rolled-out dough in the tart pan, prick the bottom with a fork, and bake for 25-30 minutes until golden. Let it cool.
Fill with Pastry Cream: Once the crust has cooled, fill it with the pastry cream and spread evenly.
Top with Fruits: Arrange the fresh fruits on top of the cream in a decorative pattern.
Glaze (Optional): Warm the apricot jam and brush it over the fruits for a shiny finish.
Tips and Variations
Fruit Choices: Use any combination of seasonal fruits; berries, stone fruits, or tropical fruits all work well.
Dietary Substitutions: For a gluten-free option, substitute the all-purpose flour with almond or coconut flour. Use a non-dairy milk for a vegan alternative to the pastry cream.
Sweetness: Adjust the sugar levels in the pastry cream according to your taste preference.
