Tart apples like Granny Smith taste best in this simple tart. Originally posted by Kathy Gunst on BabyCenter.com (http://www.babycenter.com/209_open-faced-rustic-apple-tart_400063_625.bc?scid=weekender_20101118_baby:2&pe=2UwVMVD)
To make the crust: Combine 2 cups of the flour with the salt and confectioners' sugar in the work bowl of a food processor. Pulse a few times to blend. Add the butter, and pulse about 20 times, or until the butter is the size of small peas. Add the egg, pulse to blend, and add enough of the water (a little at a time, pulsing between each addition) for the crust to stay together when you squeeze a handful of dough. Wrap the dough in plastic and chill in the refrigerator for about 30 minutes. Preheat the oven to 375 degrees. To make the filling: Mix the apple slices with the lemon juice, and set aside. Mix the remaining 1/4 cup flour with the sugar and cinnamon in a small bowl. Add half of the flour-sugar mixture to the apples, and stir gently to combine ingredients. Roll the dough out into a large 1/4-inch-thick round. Sprinkle the remaining half of the flour-sugar mixture over all except the outside 2 inches of the dough. Place the apple slices over the flour-sugar mixture in concentric circles, overlapping the slices and leaving about 2 inches of empty crust around the edge of the apples. Using your hands, fold the edge of the crust over the apples, overlapping the folds slightly and pressing the crust together with your hands where the crust overlaps. Place the remaining tablespoon of butter cubes over the top of the uncovered apples. Bake the tart for 35 to 45 minutes, until crust and apples are light golden brown and the apples are somewhat tender. Before serving, dust the tart with confectioners' sugar.
