Directions

1. Heat oven to 220C/200C fan/gas 7. Put the flour, salt and butter into a food processor and pulse until you can't feel any lumps of butter (or rub in butter with fingers). Pulse in the sugar.
2. Gently warm the buttermilk (don't throw away the pot) and vanilla in a microwave or pan. Using your largest bowl, quickly tip in some of the flour mix, followed by some of the buttermilk mix, repeating until everything is in the bowl. Use a knife to quickly mix together to form a dough - don't over-mix it.
3. Tip onto a floured surface and lightly bring together with your hands a couple of times. Press out gently to about 4cm thick and stamp out rounds with a 6cm or 7cm cutter. Re-shape trimmings, until all the dough is used. Spread out on a lightly floured baking sheet or two. Add a splash of milk into the buttermilk pot, then use to glaze the top of each scone. Bake for 10-12 mins until golden and well risen.
