This rustic tart is wonderful served warm with vanilla ice cream. To make individual galettes, roll the dough into four 8-inch circles and divide the filling among them. Flour and butter amounts are listed by weight (ounces) and by volume (cups or tablespoons). Use either measurement.
To make the dough
Combine the flour, sugar, and salt; cut in the butter until the mixture resembles coarse crumbs. Add the ice water and toss just until the mixture holds together. Be careful not to overmix. Press the dough into a ball, cover with plastic wrap, and refrigerate at least 30 minutes.
Line a baking sheet with kitchen parchment. On a lightly floured work surface, roll out the chilled dough into a 14-inch circle, about 1/8 inch thick. Transfer the dough to the prepared baking sheet and refrigerate while preparing the filling.
To make the filling
Trim the ends of the rhubarb and, if the stalks are more than 1 inch thick, cut them in half lengthwise. Cut the stalks into 1-inch-long pieces. In a large bowl, gently toss the rhubarb and raspberries with the flour and sugar. Let stand until moist, 5 to 10 minutes.
Heat the oven to 400°F. Remove the dough from the refrigerator and let sit at room temperature until it's just pliable, about 5 to 10 minutes. Gently spread the fruit in the center of the dough, leaving a 2-inch margin around the edge. Carefully fold the edge of the dough over the fruit, pleating it as you go. Brush the edge of the dough with melted butter and sprinkle with sugar.
Bake until the pastry is golden brown and the fruit is soft and bubbling, 45 to 55 min. Set on a rack to cool slightly.
