Creating an incredible Cranberry Tart can be straightforward if you follow these simple steps:

1. Prepare the Crust: In a bowl, combine the flour, granulated sugar, and salt. Cut the butter into the mixture until it resembles coarse crumbs.

2. Add Egg Yolk: Stir in the egg yolk and add ice water, one tablespoon at a time, mixing until the dough forms a ball.

3. Chill the Dough: Wrap the dough in plastic wrap and refrigerate for at least 30 minutes.

4. Prepare the Filling: In a saucepan, combine the cranberries, orange juice, sugar, cornstarch, vanilla extract, and grated orange zest. Cook over medium heat until the cranberries begin to burst and the mixture thickens.

5. Roll Out the Dough: After chilling, roll out the dough on a floured surface to fit a 9-inch tart pan. Press the dough into the pan and trim the excess.

6. Fill the Tart Shell: Pour the cranberry mixture into the prepared tart shell, spreading it evenly.

7. Preheat the Oven: Meanwhile, preheat the oven to 375°F (190°C).

8. Make Egg Wash: Beat the remaining egg and brush it over the crust for a golden finish.

9. Bake the Tart: Place the tart in the preheated oven and bake for 45-50 minutes or until the filling is bubbly and the crust is golden brown.

10. Cool the Tart: Remove from the oven and let it cool in the pan for about 15-20 minutes before transferring it to a serving plate.

11. Dust: Before serving, dust with powdered sugar for an elegant touch.

By following these steps, you will create a breathtaking Cranberry Tart that will delight everyone at your table.
