Making delicious Raspberry Vanilla Tarts involves a few straightforward steps. Here’s how to prepare them:

For the Tart Shells

1. Mix the Dry Ingredients: In a large mixing bowl, combine the flour and sugar.
2. Add the Butter: Cut the cold butter into the flour mixture until it resembles coarse crumbs.
3. Add Egg Yolk: Stir in the egg yolk until the mixture begins to come together.
4. Add Cold Water: Gradually add icy cold water, one tablespoon at a time, mixing just until the dough forms.
5. Chill the Dough: Wrap the dough in plastic wrap and refrigerate for at least 30 minutes.
6. Preheat Oven: Preheat your oven to 350°F (175°C).
7. Roll Out Dough: On a lightly floured surface, roll out the chilled dough to about 1/8 inch thickness.
8. Cut and Fit into Tarts: Cut circles of dough and gently fit them into a tartlet pan, pressing them into the grooves.
9. Prick the Dough: Use a fork to prick the bottom of each shell to prevent bubbling.
10. Bake Tart Shells: Bake in the preheated oven for 20-25 minutes or until golden. Let cool completely.

For the Vanilla Custard Filling

11. Heat the Milk: In a saucepan, heat the milk over medium heat until it’s just about to boil.
12. Whisk Sugar and Yolk: In a separate bowl, whisk together the sugar, egg yolks, and cornstarch until smooth.
13. Combine: Gradually pour the hot milk into the egg mixture, whisking constantly to temper the eggs.
14. Thicken Custard: Pour the mixture back into the saucepan, cooking over medium heat until it thickens and just begins to bubble.
15. Add Flavor: Remove from heat and stir in the vanilla extract and butter until well combined.
16. Cool the Custard: Let the custard cool to room temperature, then refrigerate until chilled.

Assemble the Tarts

17. Fill the Tarts: Once the tart shells and custard have cooled, spoon the custard into each shell.
18. Top with Raspberries: Arrange fresh raspberries on top of the custard filling.
19. Chill Again: Chill the tarts in the refrigerator for 20 minutes to set.
20. Garnish: Optionally, add fresh mint leaves for an elegant touch before serving.

With these detailed steps, you’re well on your way to creating delicious Raspberry Vanilla Tarts that will enchant everyone who tries them.
