Preheat your oven to 400 degrees.
Lightly spray a baking sheet with cooking spray.
Start by preparing the scones. In a small bowl, stir together the orange juice and half and half together.
Add the egg and beat it into the mixture.
Put the cranberries in this mixture and let them rehydrate by soaking while you move on to preparing the dry ingredients and orange glaze.
Create the glaze mixture by placing the orange juice in a small bowl.
Add the powdered sugar and beat the two together with a fork or a small whisk.
Set the glaze aside until you need it.
In a larger bowl, mix together the flour, ¼ cup of sugar, orange zest, baking powder, salt, and baking soda. Stir together with a fork.
Use a sharp knife to cut the butter into slices. This will help you more easily work it into the dry ingredients.
Using a pastry blender, cut the butter into the dry ingredients until it is combined and only tiny bits of butter remain visible. The texture of the mixture should be kind of like cornmeal.
Take the egg, milk, juice, and cranberry mixture and mix it into the dry ingredients with a large spoon. Work gently. This is not the time to beat the dough.
When you handle scone dough gently, the scones will be soft and tender. Beating this mixture only leads to tough scones. Stir just until the wet ingredients are incorporated.
If the mixture is too dry and crumbly add an extra tablespoon or two of milk.
Once the dry ingredients begin to form a ball, remove the scone dough to a lightly floured surface.
Press the dough into a disc that is about eight inches across. You don’t have to use a rolling pin; this works just as well to do it with your hands, and you won’t have one more kitchen tool to wash!
Use a very sharp knife to cut the disc into eight wedges.
Use a spatula to transfer the wedges to your prepared baking sheet. Space each wedge several inches from the others because they will expand in baking, due to the baking powder.
Using a pastry brush, brush the milk across the tops of the scones. Sprinkle sugar lightly across the tops of the scones.
Bake the scones in the oven for 15 to 20 minutes.
Let them rest for about 5 minutes before removing them with a spatula to a wire rack.
Let them cool for another 15 minutes, and then you can drizzle the glaze over the tops of the scones.
Serve immediately, slightly warm. If you have leftover scones, allow them to cool completely before storing them in an airtight container.
