1. In a large bowl, combine the flour and salt. Cut in the cold butter until the mixture resembles coarse crumbs. Gradually add the ice water, mixing just until the dough comes together.

2. Divide the dough into two equal parts, shape each into a disk, wrap in plastic, and refrigerate for at least 30 minutes.

3. In a medium bowl, toss the sliced strawberries with the sugar and cornstarch.

4. On a lightly floured surface, roll out one disk of dough to 1/8-inch thickness. Cut into heart shapes using a 3-inch cookie cutter.

5. Place a heaping tablespoon of the strawberry mixture in the center of each heart. Top with another heart-shaped dough piece and crimp the edges with a fork to seal.

6. Arrange the hand pies on a parchment-lined baking sheet. Brush the tops with the egg wash.

7. Bake at 400°F for 18-20 minutes, until the crust is golden brown. Allow to cool for 5 minutes before serving.
