Open-Faced Fresh Blueberry Pie

Directions

1. 1
   Remove the dough from the refrigerator.
2. 2
   If necessary, allow it to sit for about 10 minutes or until it is soft enough to roll.
3. 3
   Using a pastry cloth and sleeve rubbed with flour or two sheets of plastic wrap lightly sprinkled with flour, roll the dough 1/8 inch thick or less and large enough to cut a 13-inch circle.
4. 4
   Use an expandable flan ring or a cardboard template and a sharp knife as a guide to cut out the circle.
5. 5
   Transfer the dough to the pie pan, fold under the excess, and crimp the border using a fork or your fingers.
6. 6
   Cover it loosely and refrigerate it for a minimum of 1 hour and a maximum of 24 hours.
7. 7
   Preheat the oven to 425F at least 20 minutes before baking.
8. 8
   Line the pastry with parchment, pleating it as necessary so it fits into the pan, and fill it with rice or dried beans.
9. 9
   Bake for 20 minutes.
10. 10
    Carefully lift out the rice or beans with the parchment.
11. 11
    With a fork, prick the bottom and sides, and bake 5-10 minutes, or until the crust is pale golden.
12. 12
    Check after 3 minutes and prick any bubbles that may have formed.
13. 13
    Cool the crust on a rack for 3 minutes, so it is no longer piping hot, then brush the bottom and sides with the egg white.
14. 14
    Measure out 1 cup of the blueberries, choosing he softest ones.
15. 15
    Place them in a medium saucepan together with the 1/2 cup water.
16. 16
    Cover and bring them to a boil.
17. 17
    Meanwhile, in a small bowl, whisk together the cornstarch and the remaining 2 tablespoons of water.
18. 18
    Set it aside.
19. 19
    When the water and blueberries have come to a boil, lower the heat and simmer, stirring constantly for 3 to 4 minutes or until the blueberries start to burst and the juices begin to thicken.
20. 20
    Stirring constantly, add the cornstarch mixture, the sugar, lemon juice, and salt.
21. 21
    Simmer for a minute or until the mixture becomes translucent.
22. 22
    Immediately remove it from the heat and quickly fold in the remaining 3 cups of blueberries.
23. 23
    Spoon the mixture into the baked pie shell and allow to sit at room temperature for at least 2 hours before serving.
24. 24
    When set, the berries will remain very juicy but will not flow out of the crust.
25. 25
    Just before serving, if desired, pipe or spread the whipped cream around the sides of the pie, leaving the center unadorned and brilliantly glistening.
26. 26
    Room temperature, up to 2 days (without the whipped cream).
