Homemade Egg Roll

Mix egg, flour, salt and cold water to make a dough. Let dough rest 10 minutes, covered with cloth. Then knead the dough until smooth and elastic. Divide the dough into 16 portions. Roll each portion into a 6-inch square, the dough should be very thin. Stack, placing wax paper between the squares; keep cover to prevent them drying out. Fill each square with favorite filling. Seal edges by brushing with saved egg along edges. Fry at 350 degree until golden brown.
