Take one dough round out of the refrigerator and rest 15 minutes. Lightly flour your work surface. Roll the dough into a 13-inch circle.
Place the dough into an 11-inch pie dish, gently pressing it into the bottom and up the sides, at or slightly overhanging the pie pan rim.
In a mixing bowl, beat 4 of the eggs until frothy. Using kitchen shears, cut the macerated lemons into smaller pieces. Add the eggs to the lemons, and fold until combined. Pour into the prepared pie crust.
Take the other dough round out of the refrigerator and rest 15 minutes. Lightly flour your work surface again and roll the dough into a 12-inch circle.
Press the edges of the pie shell together to seal and crimp or pinch around the edge using a fork or your fingers. Freeze 15 minutes.
Remove the pie from the freezer. Cut a few decorative slits on top of the crust. In a small bowl, whisk the remaining egg. Coat the entire crust using a pastry brush.
Preheat oven to 450℉. Bake 10 minutes. Leaving the oven closed, lower the temperature to 350℉ and bake an additional 45-50 minutes. When 20 minutes remains, if the crust is getting too dark, loosely cover with aluminum foil for the remaining bake time.
Cool at least 3 hours at room-temperature prior to slicing. Serve and garnish as desired.
