• Preheat oven to 425° F.
• If using pizza stone, place in oven on middle or lower rack.
• Divide pie crust into two pieces, one slightly larger for the bottom crust and the other slightly smaller for the upper crust. Wrap upper crust piece in plastic and place in refrigerator.

Prepare bottom crust

• Mix together egg white and ½ tsp water.
  
• On pastry cloth, roll larger piece of dough until approx. 14 inches in diameter.
• Place rolled dough in pie pan.
• Brush dough in pan with egg white and water mixture.
  
• Place bottom crust in refrigerator.

Prepare filling

• Place sugar, cornstarch, and salt in mixing bowl and stir to combine.
• Add lemon zest, lemon juice, and blueberries and stir to combine.

Prepare lattice crust

• On pastry cloth, roll smaller piece of dough until approx. 12 inches in diameter.
• Using ruler or straight edge, cut rolled dough into strips approx. ¾ to 1 inch wide.
  
• Separate strips into two groups. One way to do this is to pull every other strip up a little, so that one group is the lower strips and the other group is the higher strips.
  

Fill pie and put on lattice

• Fill bottom shell with blueberry mix.
• Place one group of strips on pie, lined up in parallel and evenly spaced.
  
• Gently fold back every other strip just past center.
  
• Select longest strip from remaining group. Place strip on top of strips that have not been folded back. Position strip in the middle of the pie, perpendicular to the strips already on the pie and just before the folded-back strips.
  
• Unfold the folded strips. Fold the strips that had not been folded back. Place the third-longest strip on the pie, parallel to the strip just added to the pie.
  
• Repeat process to finish first side of pie. Then place lattice strips in the same manner on second side of pie.
  
• Using table fork, press tines into the dough on the edge of the pie pan. Position fork so that tines are pointing to middle of pie. Repeat around entire perimeter of pie.
  
• Using sharp knife, trim excess pie dough, so that crust extends to outside edge of pie pan.
  

Apply wash

• Mix together egg yolk and 1 tablespoon cream, ½ & ½, or milk.
  
• Brush mixture over all lattice strips.
  

Bake pie

• Place old chopsticks (on something similar) on 12-inch pizza pan (or similar) and then place pie on the chopsticks. This is to catch drips.
  
• Place pie and pan in oven, on pizza stone.
• If desired, after approx. ½ hour cover loosely with aluminum foil to prevent crust from burning.
• Bake until juices inside are thick, approx. 50 minutes to 1 hour and 10 minutes.
• Cool on rack at least 4 hours before cutting.
