Preheat oven to 375 degrees. Lightly grease two baking pans. Or use parchment paper.
To make the scones: In a blender or food processor, process 1/2 cup of the strawberries with the sugar and half & half or cream until the mixture is smooth. Set it aside.
In a large bowl, whisk together the flour, salt, and baking powder.
Work in the butter, using a mixer, your fingertips, a fork, or a pastry blender. The mixture should be unevenly crumbly.
In a separate bowl, whisk together the strawberry/ cream mixture, egg and vanilla.
Add this mixture to the dry ingredients, stirring until the dough just barely starts to come together.
Add the 2/3 cup of diced strawberries, gently folding them in, the dough will be quite sticky.
Drop the dough by heaping tablespoons onto the prepared baking sheets. A tablespoon cookie scoop is about perfect for this.
Make the glaze by stirring together the sugar, water and vanilla until smooth. Drizzle some atop of the scone.
Bake the scones until they're just beginning to turn golden brown around the edges, 15-16 minuets. Stick a toothpick in the center if it comes out clean they are done.
