Ingredients for the filling:
6 cups (six 1/2-pint containers) fresh blueberries, rinsed and dried
2 T cornstarch
2 teaspoons finely grated lemon zest
3 T fresh lemon juice
2/3 cup sugar (if blueberries are ripe, cut down sugar)
pinch of salt

Preparing the tart:
Preheat oven to 375 degrees. In a food processor, combine flour, sugar, salt, and butter; process until large moist crumbs form (dough should hold together when squeezed).

Transfer dough to a 9-inch round tart pan with a removable bottom; with floured fingers, press evenly into bottom and up sides. Freeze until firm, about 15 minutes; prick bottom of dough all over with a fork. Bake until golden, 20 to 25 minutes; cool completely.

Meanwhile, reserve 1 cup of the prettiest berries for topping. In a medium saucepan, bring 1/4 cup water and 1 1/2 cups berries to a boil over high heat. Reduce heat; simmer, stirring occasionally, until berries begin to break down, 3 to 4 minutes.

In a small bowl, mix cornstarch with 2 tablespoons water; stir into berries in pan. Add lemon zest and juice, sugar, and salt. Bring to a boil; reduce heat. Simmer, stirring, just until mixture begins to thicken, 30 to 60 seconds. Remove from heat. Stir in remaining 3 1/2 cups fresh berries. Immediately pour hot berry mixture into cooled tart shell, and smooth with a spatula.

Scatter reserved berries on top, pressing down lightly to help them adhere. Refrigerate until cool, about 30 minutes and up to overnight. Dust top lightly with powdered sugar just before serving.

Serves 10

Variations: This can be made with frozen blueberries; just halve the sugar.
