01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, sugar, baking powder, and salt. Stir in orange zest and chopped candied ginger.
03 - Add cold cubed butter. Using a pastry blender or fingertips, work butter into the dry mix until it resembles coarse crumbs with some pea-sized pieces remaining.
04 - In a small bowl, whisk together cream, egg, and vanilla extract until well blended.
05 - Pour wet mixture over dry ingredients. Stir gently with a fork until dough just comes together, being careful not to overmix.
06 - Turn dough onto a lightly floured surface. Pat into a 1-inch thick round. Cut into 8 wedges and transfer to prepared baking sheet, spacing 2 inches apart.
07 - Brush tops with a little extra cream for golden browning.
08 - Bake for 16-18 minutes, until golden brown and cooked through. Remove and cool on a wire rack.
09 - For optional glaze, whisk powdered sugar with orange juice until smooth. Drizzle over cooled scones.
