Preheat your oven to 350℉.
After chilling, roll the 2/3 piece into a circle 1/8” thick and use it to line the bottom and sides of the tart pan. Place in the refrigerator to chill until you are ready to fill.
Roll the remaining 1/3 of the dough and any scraps between 2 sheets of parchment paper in the shape of a rectangle 1/8” thick. Place on a sheet pan and put in the freezer for 15 minutes to firm up the dough.
Place the filling into the dough lined tart pan and smooth the top.
Remove the sheet of dough from the freezer and cut into 3/4” wide strips.
Brush the strips with the beaten egg yolk and water. I like to brush the strips with egg wash before applying , for this tart, because doing it after the strips have been applied can get a bit messy. The filling can get on the brush and get onto your strips.
Place 5 strips over the filling spaced evenly apart. The strips should hang over the edge of the pan. Cut off any excess dough even with the edge of the pan and press lightly to adhere to the crust edge.
Cut 5 more strips and place them across the existing 5 at a 45 degree angle creating a lattice pattern. Press lightly to adhere to the crust edge and remove any excess.
Bake for 40- 45 minutes or until golden brown.
Place the tart on a rack to cool about 10 minutes. Remove the tart ring and cool completely.
