Delicious Wild Blueberry Tart with a Buttery Crust

1.In a large bowl, combine the flour, sugar, and salt. Add the chilled butter and mix until the mixture resembles coarse crumbs.

2.Gradually add the ice water, mixing until the dough comes together. Form the dough into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour.

3.Preheat the oven to 375°F (190°C).

4.On a floured surface, roll out the chilled dough to fit a 9-inch tart pan. Press the dough into the pan and trim any excess.

5.In a medium bowl, combine the wild blueberries, sugar, cornstarch, lemon juice, vanilla extract, and cinnamon. Gently toss to coat the blueberries evenly.

6.Pour the blueberry mixture into the prepared tart crust, spreading it evenly.

7.Brush the edges of the crust with the beaten egg to give it a golden color when baked.

8.Bake the tart in the preheated oven for 30-35 minutes, or until the crust is golden brown and the blueberries are bubbly.

9.Remove the tart from the oven and let it cool for at least 15 minutes before slicing and serving.
