Peel and dice the mangoes and peaches into small, uniform pieces.
02 -
In a medium saucepan over moderate heat, combine the diced mangoes and peaches. Add lemon juice, sugar, and a pinch of salt. Stir in vanilla extract and simmer until fruits release their natural juices.
03 -
Add cornstarch to the fruit mixture and stir continuously until thickened. Remove from heat and transfer to separate containers to cool completely to room temperature.
04 -
On a lightly floured surface, use a rolling pin to roll out the pie pastry slightly thinner than usual. Butter a pie pan thoroughly and line with one layer of pie dough.
05 -
Roll out the second pie crust on a floured surface until it's approximately ⅛ inch thick and 12 inches in diameter. Using a sharp knife or pastry wheel, cut the dough into even strips about ½ to ¾ inch wide.
06 -
Spoon the cooled mango-peach filling into the prepared pie shell, spreading evenly to create a uniform layer.
07 -
Arrange half of the dough strips vertically across the pie, evenly spaced. Fold back alternate strips halfway, then place one horizontal strip across. Unfold the vertical strips over the horizontal one. Continue weaving remaining strips to complete the lattice pattern.
08 -
Trim any overhanging lattice strips and press them firmly into the edge of the bottom crust to create a sealed perimeter.
09 -
Brush the lattice top with egg wash and sprinkle generously with sugar. Bake at 180°C (350°F) for 25-30 minutes until the crust achieves a golden-brown color and appears fully baked.
