Ricotta Filling Combine in a large bowl all filling ingredients. Assembly Divide dough into fourths. Lightly roll each portion 1/8 inch thick and cut lengthwise into 5 inch wide strips. Use the strips immediately-do nt allow to dry. Place 2 teaspoons of the filling 1 1/2 inches from the narrow end and in the center of the strip. Continue along the strip, placing the filling at about 3 1/2 inch intervals. Fold the strip in half lengthwise, covering the mounds of filling.
