To assemble: divide the dough into two equal parts. On a large sheet of parchment paper, shape the dough into a thick, flat rectangle. Roll the dough out to slightly larger than 9x13” and a ½ inch thick. Measure and cut it to fit in the bottom of a 9x13” inch metal or glass baking pan. Carefully flip the dough into the bottom of the pan and peel back the parchment paper. Adjust the dough if necessary so that it lines the entire bottom of the pan. Evenly spread the diluted jam over the dough. Sprinkle the jam with the nut mixture. Roll out the second half of dough on parchment paper and flip onto the top of the filling. (The dough is forgiving, if it breaks, don’t stress, just patch it up as best you can).
