Preheat the oven to 400°.
In a food processor, pulse 1 1/2 cups of the flour with the salt. Add the cold butter and process just until the butter is the size of peas, about 5 seconds.
Sprinkle ice water over the mixture and process just until moistened, about 5 seconds. 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. Be sure to flour the rolling pin so the dough doesn’t stick. Just sayin’
Line a large baking sheet with parchment paper. Transfer the dough to the baking sheet.
In a small bowl, combine 2 tablespoons of sugar with 1 tablespoon of flour, and sprinkle the mixture over the dough.
Arrange the apple slices on top in overlapping concentric circles, leaving 3 inches to the edge. Fold the dough over the apples – this is rustic, so it doesn’t need to look perfect. Brush the apples with a little melted butter and sprinkle with the remaining 1 1/2 TB of sugar.
Refrigerate the unbaked tart until slightly chilled, about 10 minutes. Bake the 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.
Lightly brush the apples with the melted preserves. Slide the parchment onto a wire rack and let the tart cool slightly before serving.
Serve as is, with vanilla ice cream or whipped cream!
