Blackberry Scones

Okay so I haven't actually tried this recipe, but I think I might tonight. It looks really good... I'll let you know.

4 cups flour
4 tsp. baking powder
1 tsp. baking soda
1 tsp. cream of tartar
1/2 tsp salt
1 1/2 sticks cold butter
3/4 cup buttermilk
3/4 cup heavy cream
1 egg
2 1/2 cups blackberries, divided

Glaze
1 cup powdered sugar
1/4 milk

Mix all dry ingredients. Add cold butter that has been cut in 10-12 slices. Mix on low until pea size and still some small butter chinks are evident. Mix buttermilk, cream, and egg together until combined. Slowly pour into butter mixture with mixer running on low. Mix briefly until combined, taking care not to over beat. Pout out on floured board and knead dough four or five times; cut in half. Roll out half of the dough to about 1/2 inch thick. pour 3/4 cup blackberries over dough and fold over. Roll out once again to 3/4 inch thick; cut into 6 wedges. Repeat with the second half of dough. Place scones on greased baking sheets. Brush with some extra cream ans sprinkle with sugar. Bake at 425 for 13 (yes 13! Not 10 or 15 :) ) Pour glaze over top and sprinkle with powdered sugar.
Note: these freeze great precooked. Just let them sit out at room temperature for 45-60 minutes before baking.
