Divide dough into quarters and roll first quarter out on a floured counter into a rectangle about 12 inches wide and 7 to 8 inches long, with the wider side to you. Thinly spread jam to all but the furthest 1/4 inch from you — which seals better once rolled if bare — with about 2 to 3 tablespoons jam. (I find that with seedless raspberry, 2T covers nicely but with thicker jam, you’ll need 3T to coat it thinly. If your jam is difficult to spread, you can warm it gently in the microwave for a few seconds first.) Sprinkle with 2 tablespoons cinnamon-sugar mixture, then 4 tablespoons coarse fruit and nut mixture.
