In a mixing bowl, combine the all-purpose flour and salt. Add the chilled butter cubes and cut them into the flour mixture using a pastry cutter or two knives until it resembles coarse crumbs.
Gradually add the ice water to the mixture, stirring with a fork until the dough starts to come together. Form the dough into a ball, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
Preheat your oven to 375°F (190°C).On a lightly floured surface, roll out the chilled dough to fit your 9-inch pie dish. Carefully transfer the dough to the dish, pressing it into the bottom and sides. Trim any excess dough and crimp the edges decoratively. In a saucepan, whisk together the granulated sugar, cornstarch, salt, water, lemon juice, and lemon zest. Place the saucepan over medium heat and cook, stirring constantly with a wooden spoon, until the mixture thickens and comes to a boil.
Remove the saucepan from the heat and allow the filling to cool for a few minutes. Pour the filling into the prepared pie crust.
Arrange the fresh fruits on top of the filling, creating a visually pleasing pattern.Place the pie in the preheated oven and bake for approximately 30-35 minutes, or until the crust turns golden brown. Once baked, remove the Yippy Pie Yay from the oven and let it cool on a cooling rack. Once cooled, dust the top with powdered sugar for an extra touch of sweetness.
Slice and serve the Yippy Pie Yay, savoring each bite of its delightful combination of flavors and textures.
