Instructions

1. Preheat the oven to 375°F (190°C).
2. In a large bowl, gently combine the yellow cherries, granulated sugar, cornstarch, and lemon juice. Ensure the cherries are well coated without mashing them.
3. Roll out the pie crust on a lightly floured surface to fit a 9-inch tart pan. Carefully place the crust into the tart pan, trimming any excess dough that hangs over the edges.
4. Pour the cherry mixture into the prepared tart crust, spreading it evenly to ensure even baking.
5. Fold the edges of the crust over the cherries, creating a rustic, freeform border that allows the beautiful cherries to peek through.
6. Brush the exposed crust with the beaten egg to give it a lovely golden finish during baking.
7. Bake in the preheated oven for 40-45 minutes, or until the crust is golden brown and the cherries are bubbling and fragrant.
8. Remove the tart from the oven and let it cool for a few minutes.
9. Before serving, dust the top with powdered sugar for an elegant touch.
10. Slice into wedges and enjoy this delightful treat, either warm or at room temperature.
