Preheat oven to 400°. Line a rimmed baking sheet with parchment paper.
In a large bowl, whisk together 2¼ cups flour, sugar, baking powder, and salt. Using a pastry blender or 2 forks, cut in cold butter until it resembles coarse crumbs.
In a small bowl, combine strawberries and remaining 1 tablespoon flour, tossing to coat. Add strawberries and almonds to flour mixture, stirring gently just until combined. Add yogurt, stirring until a dough begins to form.
Turn out dough onto a lightly floured surface, and knead gently several times until a smooth dough forms. Using a rolling pin, roll out dough to a ½-inch thickness. Using a 2-inch fluted round cutter, cut 16 scones from dough, rerolling scraps as necessary. Place scones 2 inches apart on prepared baking sheet. Brush egg onto tops of scones.
Bake until scones are golden brown and a wooden pick inserted in centers comes out clean, approximately 15 minutes. Serve warm or at room temperature.
