Plump the cranberries by placing them in a small bowl and cover with warm water. Let sit for about 10 minutes, then drain well and set aside.
In a large bowl, add sugar and orange zest. Using your fingertips, rub the sugar and zest together until fragrant and resembles wet sand. Add flour, baking powder and salt and combine.
Add the butter to the dry ingredients and using a pastry cutter or your fingertips, work the butter into dry ingredients until you have butter that is pea-sized.
Add the softened cranberries and ½ cup of the cream. Toss lightly to distribute. Add 1-2 additional tablespoons of cream if too dry.
On a large lightly floured board, dump the mixture and begin to gather the dough into a mound. Flatten the mound a bit and gather any dry or loose pieces and press into the top of the dough. Using a bench scraper, fold half of the dough onto itself. Flatten a bit, give it a quarter turn and fold over the dough again, repeating the process a few times until the dough holds and you begin to see layers. Do not overwork the dough.
Shape the dough into a rectangle that's about 9"x 4" and 1" thick. Cut into 4 squares and then into triangles. You should have 8 triangles. *Feel free to make a longer rectangle and cut even smaller squares and triangles Place scones on a parchment lined baking sheet and freeze for at least 2 hours. At this point frozen scones can be placed in a freezer bag and kept frozen until ready to use, up to 1 month.
When ready to bake, preheat the oven to 375°. Place scones on a parchment lined baking sheet. Brush the top of the scones with cream and sprinkle with sugar or use turbinado sugar for an extra crunch. Bake frozen scones until lightly golden brown, about 23-25 minutes. Transfer to rack and cool slightly before serving.
