To make cornucopia, roll one-fourth of pastry into an oval, about 15x10 inches. Cut pastry oval lengthwise into 1-inch strips, using scalloped pastry cutter. Mix 1 egg and 2 teaspoons cold water. Brush 1 short strip with egg mixture; place strip, egg mixture side out, around tip of mold, forming a point. Starting with shorter strips, brush one at a time with egg mixture and carefully drape over mold, egg mixture side out, overlapping preceding strip 1/4 inch and allowing excess pastry to lie on base. Roll and cut additional one-fourth of pastry into oval, 15x10 inches. Using longer strips, continue until mold is completely covered (do not trim any excess pastry at this point). Do not cover opening with pastry. Be sure all strips are pressed securely onto preceding strips and that there are no gaps.
