01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, sugar, baking powder, baking soda, salt, and chai spice mix until thoroughly combined.
03 - Add cold, cubed butter to the flour mixture. Use a pastry cutter or fingertips to work the butter into the dry ingredients until the texture resembles coarse crumbs.
04 - In a separate bowl, whisk together heavy cream, egg, orange zest, and vanilla extract until smooth.
05 - Pour wet ingredients into the dry mixture. Stir gently until just combined. If desired, gently fold in candied ginger or golden raisins.
06 - Turn the dough out onto a lightly floured surface. Pat into a 7-inch round, approximately 1 inch thick.
07 - Cut dough into 8 wedges. Arrange pieces on the prepared baking sheet, leaving space between each wedge.
08 - Brush scone tops with a little extra cream for a glossy finish.
09 - Bake for 16 to 18 minutes, or until golden brown. Allow to cool slightly before serving.
