Preheat oven to 400℉ and line a baking sheet with parchment paper.
In a large mixing bowl, sift together the flour, sugar, baking powder, and salt. Place the bowl of flour mixture in the freezer for ten minutes. Keeping the ingredients cold will help to produce a thick, fluffy and buttery scone.
2 cups all purpose flour, ½ cup granulated sugar, 1 tablespoon baking powder, ½ teaspoon salt, ½ cup unsalted butter
Use a pastry cutter or cheese grater to cut the butter into the dry ingredients until it resembles coarse sand. If the butter begins to feel warm, pop the mixture back into the fridge for ten minutes.
Add the heavy cream, sourdough starter, egg, zest, orange juice and vanilla to the bowl and stir with a fork until well mixed. Fold in the cranberries.
3 tablespoons heavy whipping cream, 1 tablespoon orange zest, 1 tablespoon orange juice, ½ cup sourdough starter, 1 egg, 2 teaspoons vanilla extract, ½ cup dried cranberries
Turn the dough onto the parchment lined pan and shape it into a disc that is about 9 inches. This does’t need to be perfect, but a consistent thickness is key. I use my hands instead of a rolling pin to keep from smashing down the dough which would make my scones flat. If the dough isn't holding together, add cream, ½ tablespoon at a time. Likewise, if it is too wet, add flour. Cut with a sharp knife or bench scraper into wedges. Separate the wedges to 2” apart.
Place a small amount of cream in a bowl and brush the tops of the scones with the cream. Bake at 400℉ for about 20-25 minutes, depending on your oven. The scones should be just beginning to brown along the edges and a toothpick inserted into the center of a slice comes out clean.
Slide the scones with the parchment onto a wire rack to cool. While the scones are cooling, it’s time to make the orange glaze. In a small bowl, whisk together the milk, orange juice, powdered sugar, and vanilla until smooth. Drizzle over cooled scones.
1 cup powdered sugar, ¼ cup heavy whipping cream, 1 tablespoon orange juice, ¼ teaspoon vanilla extract
Enjoy! Scones will keep at room temperature in an airtight container for up to 5 days and can be frozen for up to a month!
