Dice the bacon, then brown in a skillet or frying pan until golden and crispy. Cut the butter in to cubes and set aside in the refrigerator.
In a medium bowl, mix the flour, sugar, baking powder, baking soda and salt with the cold butter by hand to form lumps no bigger than a pea.
Incorporate the cold bacon, then add the maple syrup and buttermilk and mix to a soft dough. Be careful not to overwork the dough.
Preheat the oven to 170C – 325F (gas mark 3).
Use an ice cream scoop to shape 60g (2.12oz) portions of dough in to scones and place on a baking sheet lined with parchment (baking) paper.
Brush the scones with egg yolk, then bake for 15 minutes. Drizzle the scones with maple syrup and bake for 4 more minutes.
