– Transfer the dough to a lightly floured work surface and knead 2 or 3 times, just until it comes together. Pat the dough into a disk. On a lightly floured work surface, roll out the dough into a 16- to 17-inch round, about 1/4 inch thick.
– In a small bowl, combine 2 tablespoons of the sugar with the remaining 1 tablespoon of flour and sprinkle over the dough. Arrange the apple slices on top in overlapping concentric circles to within 3 inches of the edge. Fold the dough over the apples in a free-form fashion.
– Preheat the oven to 400°F (207°C). Bake the apple tart in the center of the oven for 1 hour, or until the apples are tender and golden and the crust is deep golden and cooked through. Brush the apples with the melted preserves. Slide the parchment onto a wire rack and let the tart cool slightly before serving.
