   Transfer the dough to a cutting board or work surface. Use the heel of your hand to smear it and work it together. Divide the dough in half and form each into a 4x6 rectangle. Wrap each in plastic wrap. Store one in the freezer to use for another tart or pastry and store one in the refrigerator until firm, at least 2 hours.

   Roll out the dough by putting it between two sheets of parchment paper and rolling it into a round that is about 11 inches in diameter. Fold the dough over the rim of an 8-inch Tart Ring that is sitting on a parchment lined baking sheet.. Don't worry if it cracks or comes a part a bit, just piece it back together with any overhanging dough.

    Cut the plums into 1/8-inch thick wedges. Arrange a ring of plum slices around the outer edge of the crust so that they are facing the same direction and overlap by about two-thirds. Continue with inner, concentric layers, until the center of the tart is filled with plum slices.

    Bake for 45-60 minutes, or until the crust is well browned, the filling is set, and the plums are soft and juicy. Allow to cool completely before serving.
