Method
Heat the oven
Set the oven to 400°F and line a baking sheet with parchment.
Cut in the butter
Whisk flour, sugar, baking powder and salt. Rub in the cold butter with your fingertips until pea-sized crumbs remain.
Add the wet
Whisk buttermilk, egg and vanilla, then stir into the flour just until a shaggy dough forms.
Fold in berries
Gently fold in the berries. Don't overmix or the dough will turn purple and tough.
Shape
Pat into an 8-inch round on the sheet, cut into 8 wedges, and sprinkle with coarse sugar.
Bake
Bake 22 to 25 minutes until deep golden. Cool 10 minutes before serving.
Freeze before baking
Chill the cut wedges in the freezer for 15 minutes. Cold butter makes taller, flakier scones.
