In a bowl, combine 120g flour, 13g sugar, and 85g cold butter. Mix together until the butter resembles flakes the size of peas. This will give the crust its flaky texture.

Pour in 15g water and one egg yolk, then mix until the dough comes together. It will be shaggy and slightly dry, which is what we want.

Transfer the dough onto a piece of plastic wrap and shape it into a square. Wrap tightly and refrigerate for at least an hour, preferably overnight.

Meanwhile, prepare a double boiler by simmering a pot of water on the stove. Cover a bowl filled with 500g frozen strawberries with plastic wrap and place it on top of the pot, ensuring it is well sealed. Let it simmer for about 2 hours.

Strain out the solids and reserve the strawberry juice. Add water as needed to make 240ml (1 cup) of liquid. Set aside.

Take the pie dough out of the fridge and let it sit at room temperature for 10 to 15 minutes if it's too cold. Roll out the dough and place it over a tart form. Press it into the corners and trim off any excess dough. Prick the bottom with a fork.

Line the crust with foil and baking beans, then bake at 190°C (375°F) for 20 minutes. Remove the foil and beans, brush the crust with beaten egg, and bake for another 15 to 20 minutes or until golden brown. Allow the crust to cool.

While the crust is cooling, beat the cream cheese until smooth, then add the sour cream and mix well.

Spread the cream cheese mixture evenly over the bottom of the cooled tart shell.

Fill the tart with fresh strawberries, cutting them into halves or quarters as desired.

In a small pot, combine the reserved strawberry liquid, cornstarch (20g), and 150g sugar. Whisk continuously as you bring the mixture to a boil. Let it boil for one minute, ensuring the cornstarch is cooked out. Taste the mixture, and if the cornstarch is cooked, whisk in the juice of half a lemon.

Immediately pour the glaze over the tart and return it to the refrigerator. Let it sit for at least 4 hours or overnight to allow the glaze to set properly.

Serve the strawberry pie chilled and enjoy!
