Mill 1 2/3 cup wheat berries.
Preheat oven to 425 degrees F.
Rinse and drain the cranberries and toss with 2 tablespoons of flour. Sit aside.
In a large bowl, add the flour, salt, baking soda, and baking powder. Mix well.
Pour the olive oil over the flour mixture and use a pastry cutter or fork to mix until coarse crumbs form.
Add the milk, the juice and zest of half the orange, and the sourdough starter.
Mix until just combined. Don't over work the dough or you will have tough scones.
Fold in the cranberries.
On a lightly flour surface, turn the scone dough and gently shape into a circle that is 1/2-3/4 inch thick.
Cut the circle in half and the halves in half for a total of 8 scones.
Brush tops with milk (optional).
Bake in preheated oven for 12-15 minutes or until lightly golden brown.
While they are baking, make the glaze.
Add the sugar and zest to a small bowl. Add the juice of the other half of the orange and drizzle in just enough milk to make a glaze that can be drizzled.
Place baked scones on a wire rack and drizzle with the glaze.
