Creating the Blueberry–Lemon Curd Tart is easier than you might think. Follow these steps for a delicious result:

Prepare the Tart Crust

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Mix Ingredients: In a large bowl, combine the flour, butter, sugar, egg yolk, cold water, and salt.
3. Form Dough: Mix until a dough forms. If it’s too crumbly, add a little more water.
4. Chill Dough: Wrap the dough in plastic wrap and refrigerate for 30 minutes.
5. Roll Out Dough: On a lightly floured surface, roll out the chilled dough to fit a 9-inch tart pan.
6. Fit Dough into Pan: Press the rolled-out dough into the tart pan, trimming any excess.
7. Blind Bake: Prick the bottom with a fork and bake for 15 minutes. Let cool slightly.

Make the Lemon Curd

8. Combine Ingredients: In a medium saucepan, whisk together the sugar, eggs, lemon juice, and lemon zest.
9. Cook Mixture: Over medium heat, stir constantly until the mixture thickens and coats the back of a spoon (about 8-10 minutes).
10. Add Butter: Remove from heat and stir in the cubed butter until melted and smooth.
11. Strain Curd: For a silky texture, strain the lemon curd through a fine sieve into a bowl.
12. Cool Curd: Allow the lemon curd to cool to room temperature before pouring into the tart crust.

Assemble the Tart

13. Fill Tart: Pour the cooled lemon curd into the pre-baked tart shell, spreading it evenly.
14. Add Blueberries: Arrange the fresh blueberries on top of the lemon curd, pressing them gently into the filling.
15. Chill Tart: Refrigerate the tart for at least 1 hour to set the filling.

Serve the Tart

16. Prepare for Serving: Before serving, dust the tart with powdered sugar if desired.
17. Slice and Enjoy: Cut into slices and serve chilled or at room temperature.
