Preheat the oven to 200°C or 390°F. Line a baking tray with parchment paper. Set aside.
In a large bowl, whisk together the flour, sugar, salt, baking powder and ground ginger. Add the cubed cold butter, and working with your fingertips combine to a crumbly mixture.
In a small bowl, combine the buttermilk and egg. Add this mixture to the flour mixture gently. Mix until there is no liquid. Add in the chocolate chips and the candied ginger. Knead until everything is evenly distributed.
On a lightly floured surface, drop the dough and shape with your hands into a disc of about 20 cm. With a sharp knife, cut into 8 triangles. Place the scones on the prepared baking tray.
Brush the scones with some buttermilk and sprinkle with coarse sugar.
Bake the scones for about 20-25 minutes until they are nicely golden brown.
Let cool slightly before serving. Top with your favourite cream and jam!
