Roll one half into a 15 x 10-inch rectangle, and place on a Silpat or parchment-lined baking sheet. Spread half of the jam in a 2 1/2-inch-wide strip, lengthwise, down the center of each dough rectangle, leaving a 1-inch border at the top and bottom. Top the jam with half of the filling. Make 2-inch long slits every 3/4 inch down both long sides of the dough, toward the outer edge of the dough. Fold the top and bottom ends over the filling, folding up one inch. Starting at the top, pull one cut strip at a time up and over the filling, alternating sides so the strips overlap making it appear as though the dough is braided.
