Can I make a latticed cream pie (no-bake filling)?
The second option is your way to go. Fashion your lattice on a cookie sheet lined with parchment or Silpat that is twice the size that the lattice will be. Use dabs of pancake syrup, maple syrup, fruit syrup or egg white to seal the strips where necessary. To the side, lay out a piece of paper or cardboard and invert your pie plate on it. Draw the outline of your pie plate and cut the paper on that line. Use it as a lightweight template to trim your lattice to size. Egg wash your lattice and bake it until it reaches the color you want it to be. Let it cool so it hardens up, and then fold the excess of the parchment or Silpat mat over the lattice so you can lift it without breaking it. Slide the lattice off the parchment and onto your pie, color side up, and affix with syrup or egg white.
