Preheat the oven to 325.
Using your preferred method, cook your bacon until nice and crispy. Allow to cool, then chop up into small to coarse pieces.
Thinly slice the green onions.
Add all the dry ingredients to a bowl and mix well.
Add the butter, and work it in with a fork or pastry blender until the butter has broken down into pea sized pieces and has created a crumbly texture.
Add in your bacon and sliced green onions and mix well.
In a separate bowl, whisk together the egg, egg yolk and vinegar.
Add the egg mixture to the dough and mix well. The dough should now be coming together and starting to hold.
Line a cookie sheet with parchment paper and sprinkle it with tapioca starch.
Pour out the dough onto the cookie sheet, and sprinkle the top with a bit more tapioca flour.
Pat the dough into a circle, about 7-8 in round. It doesn’t have to be perfect, but you want the dough to be on the thick side so that the scones have a beautiful rise to the them.
With a very sharp knife, cut a “plus sign” into the dough, then cut each section into 2 to get 8 triangles. Do not move the individual scones at this point. The dough is too fragile for moving.
Place into the oven and bake for 20 min.
Remove the scones, then carefully take a knife and run it down the cuts you previously made. Gently separate the scones away from one another. Then bake for another 8 minutes. Allow to cool. Enjoy!
