2. Combine the raisins and walnuts on your cutting board and chop them finely. Transfer the mixture to a small bowl and stir in the cinnamon and vanilla.
3. Heat the oven to 325°F. Line a baking sheet with foil and set aside.
4. Lightly flour your work surface and a rolling pin. Divide the dough in half and lightly flour each piece. Roll out each piece into a 12x5-inch rectangle. Place one rectangle with the long side toward you. Brush the bottom half with half the jam. Sprinkle it with half the raisin mixture and fold the top half of the dough over it to cover the filling. Cut the folded strip crosswise into eight, 1 and 1/2-inch wide cookies. Place the cookies 2 inches apart on the baking sheet. Repeat with the remaining dough, jam and filling.
5. Bake the cookies until golden, about 30 minutes. Transfer to a rack to cool and serve.
