Arrange woven lattice decoration with 5 lattice strips spaced evenly in one direction, and another 4 at a 90° angle. Use the egg white to moisten the dough under each strip.The easiest way to weave the lattice is to gently curve back every other lattice strip. The 2nd and 4th strip curve back to just pass the center and place another strip perpendicular on top. Now uncurve the two strips so they lie flat on top of just inserted perpendicular strip. Now curve back the strips 1,3 and 5 and place another strip perpendicular on top. Follow with uncurving them flat. Turn the pie 180° and repeat the process with two more strips.
