1. Prepare the Crust:

1. In a large bowl, whisk together flour and salt. Cut in the butter until the mixture resembles coarse crumbs.
2. Gradually add ice water, 1 tablespoon at a time, until the dough comes together. Form into a disk, wrap in plastic, and chill for 30 minutes.
3. Preheat oven to 375°F (190°C). Roll out the dough to 1/8-inch thickness and cut into 4-inch circles.
4. Place a spoonful of cherry pie filling in the center of each circle. Fold over and crimp edges with a fork to seal.
5. Brush with egg wash and sprinkle with sugar. Cut small slits on top for venting.
6. Bake for 20-25 minutes or until golden brown. Let cool before serving.
