Method
- Heat the oven to 425°F (220°C), conventional top and bottom heat. Line a baking sheet with parchment.
- Whisk the flours, sugar, baking powder and salt together in a large bowl.
- Cut the cold butter into small cubes and add them to the flour. Rub it in with your fingertips until the mix looks like coarse crumbs with flakes of butter still visible. Work quickly so the butter stays cold — those visible pieces are what give you flaky layers.
- Stir the starter into the milk until loosened, then pour it into the flour. Mix with a spoon or your hand just until it comes together into a shaggy dough. It will feel soft and a little sticky — that's right. Stop mixing while it still looks rough.
- Tip the dough straight onto the lined baking sheet and pat it into one round about 1 inch (2.5 cm) thick. No floured surface, no lifting — the less you move this dough, the better it rises.
- Divide the round into 12 wedges with a bench scraper, pressing straight down rather than dragging. Leave the wedges exactly where they are, sides just touching. Brush the tops with milk.
- Bake for 22 minutes, until risen and golden. Cool on the sheet for 10 minutes, then pull the wedges apart — they'll separate cleanly along the cuts. Best served barely warm.
Notes
Chef's tip: the baking powder does the lifting here, not the starter. The starter is there for flavor and texture — it gives the crumb a gentle tang and a softness that a plain buttermilk scone doesn't have. That means you don't have to wait for it to rise: use a bubbly, recently fed starter and bake straight away.
