Free-Form Summer Fruit Tart

1. FOR THE DOUGH: Process flour and salt in food processor until combined, about 5 seconds. Scatter butter over top and pulse until mixture resembles coarse bread crumbs and butter pieces are about size of small peas, about 10 pulses. Continue to pulse, adding water 1 tablespoon at a time, until dough begins to form small curds that hold together when pinched with fingers (dough will be crumbly), about 10 pulses.
2. Turn dough crumbs onto lightly floured counter and gather into rectangular-shaped pile. Starting at farthest end, use heel of hand to smear small amount of dough against counter. Continue to smear dough until all crumbs have been worked. Gather smeared crumbs together in another rectangular-shaped pile and repeat process. Press dough into 6-inch disk, wrap it tightly in plastic wrap, and refrigerate for 1 hour. Before rolling dough out, let it sit on counter to soften slightly, about 10 minutes. (Dough can be wrapped tightly in plastic and refrigerated for up to 2 days or frozen for up to 1 month. If frozen, let dough thaw completely on counter before rolling it out.)
3. Roll dough into 12-inch circle between 2 large sheets of floured parchment paper. (If dough sticks to parchment, gently loosen and lift sticky area with bench scraper and dust parchment with additional flour.) Slide dough, still between parchment sheets, onto rimmed baking sheet and refrigerate until firm, 15 to 30 minutes. (If refrigerated longer and dough is hard and brittle, let stand at room temperature until pliant.)
4. FOR THE FILLING: Adjust oven rack to middle position and heat oven to 375 degrees. Gently toss fruit and 3 to 5 tablespoons sugar together in bowl. Remove top sheet of parchment paper from dough. Mound fruit in center of dough, leaving 2-1⁄2-inch border around edge of fruit. Being careful to leave 1⁄2-inch border of dough around edge of fruit, fold outermost 2 inches of dough over fruit, pleating it every 2 to 3 inches as needed; gently pinch pleated dough to secure, but do not press dough into fruit. Working quickly, brush top and sides of dough with water and sprinkle evenly with remaining 1 tablespoon sugar.
5. Bake until crust is deep golden brown and fruit is bubbling, about 1 hour, rotating baking sheet halfway through baking. Transfer tart with baking sheet to wire rack and let cool for 10 minutes, then use parchment to gently transfer tart to wire rack. Use metal spatula to loosen tart from parchment and remove parchment. Let tart cool on rack until juices have thickened, about 25 minutes; serve slightly warm or at room temperature.

Taste the fruit before adding sugar to it; use the lesser amount if the fruit is very sweet, more if it is tart. However much sugar you use, do not add it to the fruit until you are ready to fill and form the tart. Serve with vanilla ice cream or WHIPPED CREAM.

MAKING A FREE-FORM TART
1. For even circle, roll in short motions, working from center outward and moving dough one-quarter turn after each roll.
2. Pile fruit in center of dough, leaving 2-1⁄2-inch border around fruit.
3. Working your way around dough, gently pull up sides and create fold every 2 inches.
4. Working quickly, brush dough with water and sprinkle with 1 tablespoon sugar.
