Preheat oven to 400°(F). Line a large baking sheet with parchment paper; set aside.

In a large bowl combine flour, salt, baking powder, baking soda, and sugar; mix well to combine.

Cut the butter into small cubes then work it into the mixture until it resembles a coarse meal.

In a small bowl whisk together the egg, milk, and cream. Add to the flour/butter mixture and stir until just moistened.

Add strawberries and gently fold them into the dough.

Shape the dough into an 8-inch circle, cut it into 8 wedges, and transfer to the prepared sheet.

Lightly brush each scone with the egg wash, then sprinkle the tops with sugar.

Bake for 18 minutes, or until light golden brown.

Allow scones to cool for 10 minutes. Make the glaze by whisking together heavy cream, confectioners' sugar, vanilla, and salt. Drizzle over scones and serve at once.
