Gather all your ingredients.

In a medium bowl, sift together the flour, 3 tablespoons of sugar, and salt. Cut in the shortening until the mixture resembles coarse crumbs.

In a small bowl, beat the egg with the cold water and sprinkle it over the flour mixture. Mix with your hands to form a ball of dough. Wrap in plastic wrap and refrigerate for about 30 minutes.

Preheat the oven to 350°F (175°C). Roll out half of the chilled dough to about 1/8-inch thickness.

Place the rolled dough into a 9x13 inch baking dish, covering the bottom and halfway up the sides. Bake for about 20 minutes until lightly golden.

Combine sliced peaches, orange juice, and lemon juice in a large saucepan. Add melted butter and heat over medium-low until the butter melts.

In another bowl, mix together sugar, cornstarch, cinnamon, and nutmeg, then add to the peach mixture until well combined. Pour over the pre-baked crust.

Roll out the remaining dough to about 1/4-inch thickness. Cut into 1/2 inch strips and weave over the peach filling. Sprinkle with the remaining sugar and drizzle melted butter on top.

Place in the oven and bake for 35-40 minutes or until the topping is golden brown.
