Keep enough dough aside to make the lattice and leaf cutouts
In a large bowl mix the fruit, sugar, cornstarch, lemon juice and lemon zest and set aside.
Using your fave rolling pin, roll out the pastry dough and cut your lattice strips with a pastry cutter, and make as many leaf cutouts as you think you will need.
Put the fruit mixture in the skillet once you have all the lattice ready.
Weave the lattice over the top and have fun placing the different leaf cutouts.
Brush the top of the pie with egg white
Place the pie in the oven and bake for 15 minutes.
Reduce the heat to 375 and bake for another 35 - 45 minutes depending on your oven.
