Ingredients:
- 1 1/2 cups all-purpose flour
- 1/2 cup powdered sugar
- 1/4 teaspoon salt
- 9 tablespoons unsalted butter, chilled and cut into cubes
- 1 large egg yolk
- 2 tablespoons ice water
- 2 cups mixed berries such as raspberries, blueberries, and blackberries
- 1/4 cup granulated sugar
- 1 tablespoon cornstarch
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
- 1 egg, beaten for egg wash
Instructions:
Before you start cooking, heat the oven to 375F 190C
Pulse flour, powdered sugar, and salt together in a food processor
Pulse in the chilled butter cubes until the mixture looks like big crumbs
Whisk the egg yolk and ice water together in a small bowl
Add the egg mixture to the flour mixture slowly while pulsing the food processor
Do this until the dough comes together
Place the dough on a lightly floured surface and roll it out into a disk
The dough should be put in the fridge for at least 30 minutes after being wrapped in plastic wrap
Take a different bowl and mix together the mixed berries, cornstarch, lemon juice, and vanilla extract
Roll out the chilled dough into a circle big enough to fit into a tart pan on a floured surface
Put the dough in the tart pan and gently press it into the sides and bottom
Cut off any dough that is hanging over the pans edges
Once the crust is ready, pour the mixed berry filling into it
For a rustic look, fold any extra dough over the edges of the filling
Beating an egg and brushing it on the crusts edges will give it a golden finish
Place the tart in an oven that has already been heated
Bake for 35 to 40 minutes, or until the crust is golden brown and the filling is bubbling
Let the tart cool down a bit before you serve it
You can serve it hot or cold
