See the video below on how to accurately measure flour without a scale.
Mix all the dry ingredients together in a bowl, except the blueberries.
Cut the butter into the dry ingredients using your hands or a pastry mixer. The dough should have coarse pieces of butter visible still.
Mix all the wet ingredients together and add to the dry.
Use a fork to combine the wet and dry ingredients. Mix until the dry ingredients are just moistened.
Let the dough rest for 5 minutes and then stir in the blueberries. Don't overmix or the scones will be tough and dry.
Turn dough out on a lightly floured surface and gently shape the dough into an 8-inch disc.
Cut the disc into 8 pie-shaped pieces. Place the pieces on a parchment-lined or greased baking sheet.
Bake for 20 minutes at 375 degrees.
